Find the inverse of the function. f(x) = 7x + 8

The inverse of the function f(x) = 7x + 8 is

The given function is:

f(x) = 7x + 8

Make x the subject of the formula:

Divide through by 7

Replace x by and f(x) by x

The inverse of the function f(x) = 7x + 8 is

Step-by-step explanation:

A way to find the inverse function is to swap the x and y (f(x)) in the equation.

We can check that it is an inverse function by using a property of inverse functions:

If we plug in the f(x) function into the variable x of the inverse function, we should end up with x

It checks out!

the square root of what number? if you add that, then someone will probably answer the question.

step-by-step explanation:

consider an orange peel: if you want to try and lay it flat, you have to stretch it, we know exactly how things are being stretched or squashed at any given point. we have many different map projections because each has different patterns of some projections can even preserve certain features of the earth without
