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
bogdanovich [222]
Hi there!

m(x) = 5x - 5
First replace m(x) by y.

y = 5x - 5
To find the inverse function we must switch the places from the variables x and y.

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

x + 5 = 5y
Switch sides.

5y = x + 5
And finally divide both sides by 5.

y =  \frac{x + 5}{5}
And therefore we can conclude the following:

m {}^{ - 1} (x) =  \frac{x + 5}{5}
The answer is C.
~ Hope this helps you!
