Find the inverse function of m(x) = 5x - 5 a m-1(x) = 5x + 5 b m-1(x) = -5x + 5 c m-1(x) = x+5/5 d m-1(x) = x+5/-5x

Switch your X and Y =

x = 5y - 5

Add 5 to both sides

x +5 = 5y

Divide both sides by 5

M -1 (x) = x+5/5

Hi there!


First replace m(x) by y.


To find the inverse function we must switch the places from the variables x and y.


Now we need to isolate the y again to find the formula of the inverse function. First add 5 to both sides.


Switch sides.


And finally divide both sides by 5.


And therefore we can conclude the following:


The answer is C.
~ Hope this helps you!

The answer is 1 because you have to flip the sign when dividing by negative number and 3
