09-04 Inverse Functions

Front

What is NOT TRUE about inverse functions? Options: Inverse functions are reflections of each other over the line y = x. You find the inverse by switching x and y in the equation. You find the inverse by switching x-values and y-values in the table. Inverse functions always have the same domain and range.

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

Which is f ^-1(x)?

Options:

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

,

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

,

f ^-1(x) = 3x - 15

,

f ^-1(x) = 3x + 15

Back

Which is g ^-1(t)?
Options:
g ^-1(t) = 1/6(t) + 1/6
g ^-1(t) = 6t + 1
g ^-1(t) = 1/6(t) + 1
g ^-1(t) = 1/6(t) + 6

Back

g ^-1(t) = 1/6(t) + 1
