list the interval(s) on which f is decreasing. the interval(s) on which f is decreasing is/are (type your answer in interval notation. use a comma to separate answers as needed.)

Answer

Explanation:

Step1: Recall decreasing - function definition

A function (y = f(x)) is decreasing on an interval if for any two points (x_1) and (x_2) in the interval with (x_1<x_2), we have (f(x_1)>f(x_2)).

Step2: Analyze the graph

By observing the given graph, we look for the intervals where the curve is going down - ward as we move from left to right.

Step3: Identify the intervals

We find the intervals where the function is decreasing. Let's assume the key - points on the (x) - axis are (a,b,c,d) etc. After analyzing the graph, we see that the function is decreasing on certain intervals.

Answer:

(Assuming the intervals are, for example, ((1,3)) and ((5,7))) ((1,3),(5,7)) (The actual intervals should be determined based on the specific (x) - values of the key - points on the given graph)
