What is the inverse of the function y=-x-1
Swap x and y to go from y = -x-1 to x = -y-1
Then solve for y
I did and I got the same as before I did the inverse... is that correct?
that is correct, the reason why is because y = -x-1 is perpendicular to y = x
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)
