Question

if f(x)=-5x-13 than f^-1(x)=?

Answer 1

the first step is to solve y=-5x-13
for x.

Answer 2

For example,
I bet you know how to solve 5=-5x-13 for x.
You would add 13 on both sides right?
5+13=-5x

then divide both sides by -5
(5+13)/(-5)=x

just do the same thing here but instead of 5 you have y

Answer 3

I would add 13 to both sides and divide both sides by -5 which i guess would leave me with 5=x

Answer 4

I don't understand how to do the same with y though

Answer 5

first add 13 to both sides
