Inverse Functions Practice

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 
f(x)=2x-2
     

• f^-1(x)=1/2x+1
• f^-1(x)=-2-1/2x
• f^-1(x)=-7/3x-20/3
• 2-2/5x

Are the blue and red graphs inverse functions?

• yes
• no
• no way to tell

Are these inverse functions?

• no
• yes
• no way to tell

If f^-1(-25) = 7 then what is f(7) = 

• 25
• 7
• No enough information. 
• -25

Match each function with its inverse.

• f(x) = x² - 5

• f^-1(x) = ∛(x-5)

• f(x) = x³ + 5

• f^-1(x) = (x+5)²

• f(x) = √(x) - 5

• f^-1(x) =√(x+5)

• f(x) = (x - 5)²

• f^-1(x) = √(x) + 5

Find the inverse of
f(x) = 1/4x - 7

• f^-1(x) = 4x + 7
• f^-1(x) = -4x + 28
• f^-1(x) = -4x - 7
• f^-1(x) = 4x + 28
