Determining If Functions Are Inverse

In an inverse function, the _____ and _______ are switched from the original

• f(x) and g(x)

• input and output

• positives and negatives

• slope and intercept

Given f(x) = x+3, find f^-1(-2).

• -1

• 1

• 5

• -5

Find the inverse of f(x) = x² - 5

• f^-1(x) = √(x) + 5

• f^-1(x) = ∛(x-5)

• f^-1(x) =√(x+5)

• f^-1(x) = x² - 5

The inverse has been reflected over which line?

• y = x

• y =1

• y = 0

• y = x + 1
