Inverse Functions Cubic

The inverse has been reflected over which line?

• y = x

• x = 0

• y = 0

• x = -y

What transformations have occurred to get the graph of g(x) from the graph of f(x)?

• vertical shrink by a factor of 1/4,translation down 2 units

• vertical shrink by a factor of 1/4,translation right 2 units

• vertical stretch by a factor of 1/4,translation down 2 units

• vertical stretch by a factor of 1/4,translation right 2 units

What's the best description?

• They are both functions, but not inverse functions.

• They are reflected over y=x, but they are not both functions.

• They are not reflected over y=x, and they are not both functions.

• They are inverse functions.

What are the missing values if g(x)=f^-1(x)?

• (9,-5)

• (-9,-5)

• (5,9)

• (-9,5)

Which is f^-1(x)?

• f^-1(x)=4+∛(x+5)

• f^-1(x)=∛(x+4) +5

• f^-1(x)=5+(x+4)³

• f^-1(x)=4+(x+5)³

• A
• B
• C
• D

Find the inverse of y = x³ + 7

• y = ∛(x-7)

• y = ∛x -7

• y = (x - 7)³

• y = x³ - 7

What is the inverse of f(x) = (x-9)³? Remember that the x and y switch.

• f^-1(x) = x^1/3 + 9

• f^-1(x) = x^1/3 - 9

• f^-1(x) =(x + 9)^1/3

• f^-1(x) =(x - 9)^1/3

• y = 6∛x - 5

• y = ∛(x+5/6)

• y = (6x - 5)³

• y = (1/6x+5)³

Which is f^-1(x)?

• f^-1(x)=3∛(x-6)

• f^-1(x)=-6+3∛x

• f^-1(x)=∛(3x-18)

• f^-1(x)=3(x-6)³
