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

Back

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

Front

What are the missing values if g(x)=f^-1(x)? Options: (9,-5), (-9,-5), (5,9), (-9,5)

Back

(9,-5)

Front

Which is f ^-1(x)? Options:

f ^-1(x) = 5x + 3

,

f ^-1(x) = 5x - 3

,

f ^-1(x) = 5x - 15

,

f ^-1(x) = 1/5(x) + 3/5

Back

f ^-1(x) = 5x - 3

Front

Which is f ^-1(x)?
