1. The problem statement, all variables and given/known data
f(x,y) = $\sqrt{1+9xy}$, y = $x^{3}$ for 0≤x≤1

2. Relevant equations

3. The attempt at a solution
I don't even know how to start this problem. I thought about c(t) since that's all I have been doing, but there isn't even c(t). I only recognize domain. Can anyone help me please?
