WebIf f ′ ( x) > 0 on an open interval, then f is increasing on the interval. If f ′ ( x) < 0 on an open interval, then f is decreasing on the interval. DO : Ponder the graphs in the box above until you are confident of why the two conditions listed are true. You should completely master this concept; a helpful shorthand: f ′ > 0 f ↑ WebMath Advanced Math The relation ★ is defined on Z-{0} by xy if and only if every prime divisor of x is a divisor of y.
