Let f(t) be the function whose graph is presented below. f(t) -1 Define F(x)= - 1 a. What is F(-1)? b. Find all points z on 1-1,4] at which the derivative F'(x)=0. e. For what value of the constant C is the function F(z) + C the solution of the initial value problem y(x)=f(x), y(3) = 0. where the function f(x) is still the function whose graph is at the beginning of the problem. The values of f(t) for any integer t may be derived from the graph. Same for ff(t) dt for any integers a and b. f(t) dt.
