Exercise 22 Page 424

Find the intervals in which the values of the functions decrease as the x-values increase.

Table:

Function Decreasing Interval
f(x) x<0
g(x) x>0
Practice makes perfect

To find the decreasing interval, we will scan the graph from left to right.

The orange arrows shows decreasing intervals of the functions. From left side of graph to x=0 & → && f is decreasing From x=0 to right side of graph & → && gis decreasing For all x-values less than x=0, f will be decreasing. Additionally, for all x-values greater than x=0, g will be decreasing.

Function Decreasing Interval
f(x) x<0
g(x) x>0
