Which of the following is the result of applying the substitution $u=4 x-9$ to the integral $\int_{2}^{8}(4 x-9)^{20} d x ?$ (a) $\int_{2}^{8} u^{20} d u$ (b) $\frac{1}{4} \int_{2}^{8} u^{20} d u$ (c) $4 \int_{-1}^{23} u^{20} d u$ (d) $\frac{1}{4} \int_{-1}^{23} u^{20} d u$ In Exercises $83-84,$ compute the definite integral two ways: - Multiply out the integrand and then integrate directly without a substifution. - Use the Change of Variables Formula with the substitution provided.
