INCREASING AND DECREASING FUNCTIONS

CONTINUITY ON A CLOSED INTERVAL. A function f is . continuous on an closed interval [a, b], if it is continuous on the open interval (a, b) and: and . Basically, the endpoints need to fill filled-in pieces of the graph. EXAMPLE 4: Discuss the continuity of . For this radical function, it is clearly continuous on the open interval (-1, 1). And since ................
