Best ResponseYou've already chosen the best response.1You need to do a u substitution. you have this right now:\[\int\limits_{2}^{5}h(x)dx = 11\]and the question is:\[\int\limits_{0}^{7}h(x2)dx=?\]So start with:\[\int\limits_{0}^{7}h(x2)dx\]Let u = x2, then du=dx, and your lower limit changes to:\[02=2\]while your upper limit becomes:\[72=5\]So with your substitution in place, you see that:\[\int\limits_{0}^{7}h(x2)dx=\int\limits_{2}^{5}h(u)du\]
