If f(x) = , what is the equation for f–1(x)?

f–1(x) = 4(x + 3)

f–1(x) = 4x - 3

f–1(x) = 4(x - 3)

f–1(x) = 4x + 3

option (b) is correct

inverse of function   is 4x+3

Step-by-step explanation:

Given function

We have to find the inverse of given function.

Let f(x) = y then taking inverse both sides, we get

Substitute , x  and f(x) in given equation, we get,

Now solve for , we get,

Thus, inverse of function   is 4x+3

Thus, option (b) is correct.
