Inverse Relations

What is the RANGE of the INVERSE function?

• <-5, 1, 3, 4>

• <-4, -3, -1, 5>

• <-4, -2, 0, 7>

• <-7, 0, 2, 4>

If the DOMAIN of a function is (-∞, 2], then the DOMAIN of the INVERSE function will also be (-∞, 2].

• false

• true

  R: [3, ∞)

What is the inverse quadratic function?

• f^-1(x) = x²

• f^-1(x) = ±√x

• f^-1(x) = -x²

• It doesn't have an inverse.

The inverse has been reflected over which line?

• y = x

• y =1

• y = 0

• y = x + 1

What does it mean to find the inverse of a function?

• the x's and y's are switched

• the x's and y's are divided by 2

• the x's and y's are made negative

• the x's and y's are the same
