Subject: Optimizing Functions
Question
Hi! I just wanted to know some easy steps to optimizing functions. I have a Calculus final in two days, and this is the only thing that is difficult for me.
Answer
To optimize a problem, set the derivative, f'(x), equal to 0 and solve for x, giving x0.
If the second derivative, f"(x0), is negative at this value, then the point is a maximum value for local x in f(x).
If the second derivative, f"(x0), is positive at this value, then the point is a minimum value for local x in f(x).
