Find the inverse of f(x) = -4x - 12

• f^-1(x) = 4x - 3

• f^-1(x) = -1/4x - 3

• f^-1(x) = 1/4x + 3

• f^-1(x) = -4x - 3

Are f(x) =x+6 and g(x) =x-6 inverses?

• Yes

• No

The inverse of the function f(x) is written as ...

• f ^-1(x)

• f ²(x)

• f '(x)

• f ⁺(x)

To prove two functions are inverses of each other, both f(g(x)) and g(f(x)) should equal...
