Inverse Functions Practice

The inverse of the function f(x) is written as ...

• f ^-1(x)

• f ²(x)

• f '(x)

• f ⁺(x)

The inverse has been reflected over which line?

• y = x

• x = 0

• y = 0

• x = -y

Which of the following is NOT TRUE about inverse functions?

• Inverse functions are reflections of each other over the line y = x.

• You find the inverse by switching x and y in the equation.

• The domain of a function becomes the domain of its inverse.

• The domain of a function becomes the range of its inverse.

What is f^-1(x)?

• f^-1(x) = 4x - 3

• f^-1(x) = -1/4x - 3

• f^-1(x) = 1/4x + 3

• f^-1(x) = -4x - 3

Is the inverse function found correctly?

• yes

• no
