Consider the function f(x)=4 sin x+x2+5x –10 with domain the closed interval [0, 27]. (a) Show that f(x) is increasing on its domain. Explain clearly your reasoning. (b) Find the interval(s) where f(x) is concave up and the interval(s) where it is concave down, and any points of inflection. Show your work.
