determine the intervals on which the function is (a) increasing, (b) decreasing, (c) constant. (a) the function is increasing on the interval(s) (use a comma to separate answers as needed. type your answer in interval notation.)
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 $f(x_1)<f(x_2)$. Visually, the graph of the function rises from left - to - right.
Step2: Analyze the given graph
Looking at the graph, we see that the function rises from $x=-3$ to $x = 1$.
Answer:
$(-3,1)$
