In this problem we find the absolute maximum and minimum for the function f(x) = 23 - 3x2 -9x over the interval [-2, 5]. Let us break this down into steps as follows. . Step One. Compute f' (x). . Step Two. List all the critical points of f within [-2, 5). . Step Three. Find the values of f at the critical points and the values at the endpoints. . Step Four. Write down your conclusion based on the above values
