Question 643521: I'm having problems with a question
it is find the inverse of f(x)=e^(x-5)-5
I have taken y and substituted for x to get
x=e^(y-5)-5 then
5+x= e^(y-5)
I'm not sure if I'm doing this right and where to go from here

Question 643875: I am trying to test an equation for symmetry. The equation is x^2 - y^3 + 4.
I am starting by trying to find the intercepts. I think I found the intercepts for x - (2,0), (-2,0). I am having trouble finding the intercepts for y.
I substitute 0 for X and get 0 + y^3 + 4. I convert that to y^3 = -4. I am not sure where to go from there. Can I get a cube root of four? Solving for y, would my answer be the cube root of four i? Does that mean there is no y intercept?
I've confused myself... Thanks for any help.
