list the interval(s) on which f is decreasing. the interval(s) on which f is decreasing is/are . (type your…

Explanation:

Step1: Identify decreasing - part of graph

A function is decreasing when as (x) increases, (y) decreases. Looking at the graph, we can see the function is decreasing on two intervals.

Step2: Determine first decreasing interval

From (x=-10) to (x = - 6), the (y) - values are getting smaller as (x) increases. In interval notation, this is ((-10,-6)).

Step3: Determine second decreasing interval

From (x = 0) to (x=2), the (y) - values are getting smaller as (x) increases. In interval notation, this is ((0,2)).

Answer:

((-10,-6),(0,2))
