Let p(x)=2x^3-113 and let q be the inverse of p. Find q(137). Please explain in steps.

I posted this already but I did not list my steps. The first step would be to find the inverse of 2x^3-113 which would be: y=(x+113/2)^1/3. and then would I just plut in 137 for x?

q = [ (x+113)/2 ]^1/3

q = [ (137+113)/2 ]^1/3

q = 125^1/3 = 5
