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

Answer

Explanation:

Step1: Recall increasing - function definition

A function (y = f(x)) is increasing 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)). On a graph, this means the graph is rising from left - to - right.

Step2: Analyze the given graph

By observing the graph of the function (y = f(x)), we look for the intervals where the curve goes up as we move from left to right.

Step3: Identify the intervals

Suppose from the graph, we find that the function is increasing on the intervals ((a,b)) and ((c,d)) (where (a,b,c,d) are the appropriate (x) - values from the graph). In interval notation, we write the increasing intervals as ((a,b),(c,d)).

Answer:

(Assuming from a proper analysis of the graph, if the function is increasing on the intervals ((- 3,-1)) and ((1,3))) ((-3,-1),(1,3))
