y can not be isolated here.
y = 5x^3 - x^5
I know that you switch the y and x values around, so the new equation is:
x = 5y^3 - y^5
However, I don't know what to do next in order to isolate y. Any suggestions would be greatly appreciated. Thank you in advance!
If only you would plot this function, you would see there is no inverse.
