Determine the intervals on which the function is increasing

Determine the intervals on which the function is increasing, decreasing, and constant.

A) Increasing on (5,10); Decreasing on (0,5)

b) Increasing on (5,10); Decreasing on 0,5); Constant on (10,?)

c) Increasing on (5,6); Decreasing on (0, 5); Constant on (6,10)

d)   Increasing on (-2,1); Decreasing on (-2,5); Constant on (6,10)

Solution

From the graph we can see that function is decreasing continously from 0 to 5 and then after that increasing continously from 5 to 6 and then constant from 6 to 10
