1. The problem statement, all variables and given/known data I'm helping my friend review for his exam in precalc and I can't seem to get this inverse. Find the inverse of y=x^3 + x +4 2. Relevant equations 3. The attempt at a solution I switched the variables and then tried to isolate the y but I failed. I ended with x-4=y^3+y I don't know how to isolate the y from here how would you go about it?
