Unit 6 Part 2 Test Review

Front

If f^-1(-25) = 7, what is f(7)?

Back

f(7) = -25

Front

Which function matches the graph? A: f(x) = ∛(x + 3) + 2, B: f(x) = − ∛(x - 3) + 2, C: f(x) = ∛(x - 3) + 2, D: f(x) = ∛(x - 2) + 3

Back

C: f(x) = ∛(x - 3) + 2

Front

Find h(f(-2)).

Back

h(f(-2)) = 2

Front

What is the domain of the graph of the radical function? (-∞, ∞), (-7, ∞), (0, ∞), (4, ∞)

Back

Domain = (4, ∞)

Front

Back

Yes, f and g are inverses.

Front

What is the definition of an inverse function?

Back

An inverse function reverses the operation of the original function.

Front

How do you find the inverse of a function algebraically?

Back

To find the inverse, swap x and y in the equation and solve for y.

Front

What is the range of a function?

Back

The range is the set of all possible output values (y-values) of a function.

Front

What is a radical function?

Back

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

Front

What does it mean for two functions to be inverses?

Back

If f(g(x)) = x and g(f(x)) = x, then f and g are inverses.
