question 21 consider the function in the graph to the right. the function is increasing on the interval(s): the function is decreasing on the interval(s):
Answer
Explanation:
Step1: Identify increasing intervals
A function is increasing when the graph goes up - as - we - move from left to right. From the graph, the function is increasing on the intervals $(-\infty,-1.9)$ and $(1.2,\infty)$.
Step2: Identify decreasing intervals
A function is decreasing when the graph goes down - as - we - move from left to right. From the graph, the function is decreasing on the interval $(-1.9,1.2)$.
Answer:
The function is increasing on the interval(s): $(-\infty,-1.9)\cup(1.2,\infty)$ The function is decreasing on the interval(s): $(-1.9,1.2)$
