WebYou have to realize if h>0, then c-h is the x-value of some point to the left of c, and c+h is the x-value of some point to the right of c. Thus, the open bound (c-h, c+h) includes all x strictly between those two points. And if we say f (c) is a relative minima, we are really saying f (c) is less than all f (x) in the interval (c-h, c+h).
