# What are the domain and range of f(x) = 2(3x)??

Answer: The domain and the range of the function f (x) = 2 (3x) is ( - ∞, ∞).

## With allowance for this, what is the domain of f/x )= 3x 2?

We get, f(x) = 3x - 2 is also a polynomial function. Therefore, its domain is also 'all the real numbers'.

## With this in view what is the domain and range of f/x 3x?

Algebra Examples The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. The range is the set of all valid y values.

## Furthermore, what is the range of the function f/x x2 3?

Answer: The range of f(x) = x2 + 3 is [3, ∞).

#### What is the range of f/x )= 2?

The domain of the function is the set of real numbers R. The value of f(x) = |x - 2| is never negative,. For value of x < 2, the function f(x) = 2 - x which is positive. The range of the function is therefore the set .

#### What is range and codomain?

The codomain is the set of all possible values which can come out as a result but the range is the set of values which actually comes out.

#### What is the domain of 3x?

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. The range is the set of all valid y values.

#### What is y 3x 5 on a graph?

The equation y=−3x+5 is in slope intercept form, and represents a straight line in which -3 is the slope, and 5 is the y -intercept.

#### What is the domain What is the range?

The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes.

#### What is the domain and range of 3x 1?

Explanation: y=3x+1 is defined for all Real values of x ; therefore the Domain is all Real values. Re-arranging as y−13=x , we can see that this is also defined for all Real values of y ; therefore the Range is all Real values.

#### What is the range of the function f/x x2?

The function f(x) = x2 has a domain of all real numbers (x can be anything) and a range that is greater than or equal to zero.

#### What is the domain for 3x 1?

The domain of the expression is all real numbers except where the expression is undefined.

#### What is the domain of 3x 9?

The domain of the expression is all real numbers except where the expression is undefined.

#### What is the range of x 2?

For example, the function x2 takes the reals (domain) to the non-negative reals (range). The sine function takes the reals (domain) to the closed interval [−1,1] (range).

#### What is the domain for f/x )= 3 x?

The domain of the expression is all real numbers except where the expression is undefined.

#### Is 5 y 3x a linear equation?

Thanks. it is a linear equation because the highest order of exponents is equal to 1.

#### What is the domain in math?

The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited.

#### What is the domain and range?

Domain and Range. The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.

#### What is the domain of X?

The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes.

#### What is a domain in math?

The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes. (In grammar school, you probably called the domain the replacement set and the range the solution set.

#### What's the domain of 3x 2?

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.

#### What is a domain in math example?

The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited.

#### What is domain and range examples?

Example 2: The domain is the set of x -coordinates, {0,1,2} , and the range is the set of y -coordinates, {7,8,9,10} . Note that the domain elements 1 and 2 are associated with more than one range elements, so this is not a function.

#### What is the range of f/x )=- 3x 2 5?

The range is either y≥−5 or y≤−5 . Since a is positive, the parabola opens upwards. So the range has to be y is greater than or equal to something. So the range is y≥−5 .

#### What is the range of f/x 3x 9?

The range of f(x) = 3x + 9 is all real numbers.

#### How do you find the domain?

Functions assign outputs to inputs. The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0.

#### How do you find the domain and range of a function X?

The domain is part of the definition of a function. For example, the domain of the function f(x)=√x f ( x ) = x is x≥0 x ≥ 0 . The range of a function is the set of results, solutions, or ' output ' values (y) to the equation for a given input. By definition, a function only has one result for each domain.

#### What is the domain of x 3?

Explanation: x3 is a polynomial, which means its domain is R , and in our case, its range is also R because the only root that x3 has, 0, is not a double root (technically it's a triple root, and because 3 is odd, the function switches sign).

#### Is domain left to right?

Note that the domain and range are always written from smaller to larger values, or from left to right for domain, and from the bottom of the graph to the top of the graph for range.
