RE: [apcalculus] Number System

I am working in the new, 9th edition, of D & S and am stuck on free response question 4(c). The tangent line is y7=10(x3) and I cannot understand where the ten comes from. W'(x) should be the derivative of an integral, which I believe is the integrand evaluated at the upper bound, which gives me w'(x)=g(f(x)), yet w'(3)=g(f(3))=2. Any help would be appreciated!
