Question

8 Peaks and valleys The question here is simple to ask: what is the relation between a) peaks and valleys of the graph of a function f and b) peaks and valleys of the graph of f2? You'll want to consider several kinds of situations. For example, if f can be negative, things are different than if f is never negative. Which situation is simpler? Don't just focus on the simple situation! Also, how small can the square of a function possibly be? If /2 ever gets this small, does it necessarily have anything to do with f having a peak or valley at that point?
