If f(x) and f^-4(x) are inverse functions of each other and f(x) = 2x+5, what is f^-1(x)?
miss Akunina [59]

For this case we must find the inverse of the following function:

f (x) = 2x + 5

Then, we follow the steps:

We change f (x)by y:

y = 2x + 5

We exchange the variables:

x = 2y + 5

We clear the variable "y":

x-5 = 2y\\y = \frac {x-5} {2}

We change y for f^{-1}(x):

f^{-1}(x) = \frac {x-5} {2}

Answer:

f^{-1}(x) = \frac {x-5} {2}
