Question

Write the inverse function for the function, ƒ(x) =x + 4. Then, find the value of ƒ -1(4). Type your answers in the box.

ƒ -1(x) =
ƒ -1(4) =

Answer 1

Answer:

ƒ -1(x) = x - 4

ƒ -1(4) = 0

Explanation :

Let f(x) = y,

Then, y = x +4

x = y - 4

f^(-1) x = x - 4

f^(-1)4 = 4 - 4 = 0

Answer 2

Answer:

ƒ -1(x) = x - 4

ƒ -1(4) = 0
