Question

What is the inverse of the function y=-x-1

Answer 1

Swap x and y to go from

y = -x-1

to

x = -y-1

Answer 2

Then solve for y

Answer 3

I did and I got the same as before I did the inverse... is that correct?

Answer 4

that is correct, the reason why is because y = -x-1 is perpendicular to y = x

Answer 5

if you reflect y = -x-1 over the line y = x, you'll see that the line y = -x-1 will reflect over itself (ie it's symmetrical about the line y = x)

Answer 6

Thank you!
