1. Find all maxima and minima, including at endpoints, of f(x) = x (120 - 2x) on the . horizontal span of 0 to 60. (Enter the maximum and minimum values of f, not the value of x at those points.) (max) (min) 2. ind the minimum value of the function. f(x) = 4+5x+2x X 3. If f(x) = x + 5x + 2, evaluate the following: f(-2) = 4. Determine whether the given function has a maximum value or a minimum value, and then find the value. f(x) = -x + 40x-4 The function has a maximum value when x = The value of f(x) at this point is .
