Consider the function F(x)=e−x+x2F(x) = e^{-x} + x^{2}, 0≤x≤40 \le x \le 4. (a) Show that FF is continuous on [0,4][0,4] and differentiable on (0,4)(0,4). (b) Find F′(x)F'(x) and prove that there is exactly one critical point cc in (0,4)(0,4). (c) Compute F′′(c)F''(c) and classify the critical point. (d) Evaluate FF at x=0x = 0, x=4x = 4, and x=cx = c. Use these values to identify the absolute minimum of FF on [0,4][0,4] and justify your conclusion. (e) Determine the absolute maximum value of FF on the interval and locate where it occurs.
