MESSAGE ME FOR GRAPH Let f be the continuous function defined on [−3,7] whose graph, consisting of two line segments, is shown above. Let g and h be the functions defined by g(x)=(x^2+5x)^1/3 and h(x)=7cosx+x^3. (a) The function N is defined by N(x)=f(x)g(x). Find N′(−1). Show the work that leads to your answer. (b) The function P is defined by P(x)=g(x)5f(x). Find P′(4). Show the work that leads to your answer.(c) Find the value of x for −3
