I need help from anybody who knows calculus somewhat well. Here's a question that has been posing me problems:
Basically I have a flat line at y = 2 (arbitrarily), then it takes two dips, the first dip at x = 2 and the second at x = 4. After each dip, the function comes back to the y =- 2 line and never gets higher than that, so there should not be a global or local max, right?
