Need help estimating integrals

Question

Estimate the integral ∫15(top)3(bottom)(−x2+0.07x−0.9)dx
using a right Riemann sum with 6 subintervals.

Answer 1

you will need to evaluate the integrand (polynomial) at x = 5, 7, 9, 11, 13 and 15.  these values will be heights of rectangles, and each will have a base 2.  compute those six area and add them.
