Hey everybody! My question is: Find the value of x that maximizes the following function and the maximum value (a is constant): f(x) = x^2 subject to 0 ≤ x ≤ a. It is supposed to be solved without calculus and I'm terrible confused! how would i go about solving this? wen i plot the curve i of course get half a parabola (positive half), and given the constraint 0 ≤ x ≤ a, the graph gets limited. Im confused what the answer to this question would be :s! would it be a^2 as the maximum value and a as the value of x that maximizes the function, or would it simply be 0 or not possible?!? any help would be appreciated greatly!
