WebSince f f is increasing on the interval [-2,5] [−2,5], we know g g is concave up on that interval. And since f f is decreasing on the interval [5,13] [5,13], we know g g is concave down on that interval. g g changes concavity at x=5 x = 5, so it has an inflection point there. Problem 1 This is the graph of f f.

WebIf the functions f and g are decreasing functions on an open interval I, then the sum of the functions f + g is also decreasing on this interval. If the function f is an increasing function on an open interval I, then the opposite function -f is decreasing on this interval. WebWe use this test in several ways.
