Unit 3 Test Review

Front

What is the domain of the graph of the radical function?

Back

The domain is [4, infinity).

Front

Are these functions inverses?

Back

No.

Back

No Solution.

Front

Back

The y-intercept is (0, 3).

Front

Back

Subtract 12 from both sides of the equation.

Front

Define a radical function.

Back

A radical function is a function that contains a variable within a radical (square root, cube root, etc.).

Front

What is the range of a square root function?

Back

Front

How do you find the y-intercept of a function?

Back

Set x=0 and solve for y.

Front

What does it mean for two functions to be inverses?

Back

Two functions are inverses if their compositions yield the identity function, i.e., f(g(x)) = x and g(f(x)) = x.

Front

What is the process to solve a radical equation?

Back

Isolate the radical, square both sides, and solve for the variable.
