Question

determine all intervals on which the graph of f is decreasing. graph of f answer attempt 1 out of 2

Explanation:

Step1: Recall decreasing - function property

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

Step2: Identify intervals from the graph

By observing the graph of \(y = f(x)\), we see that the graph is decreasing on the intervals \((-5,-2)\) and \((1,3)\) and \((4,\infty)\).

Answer:

\((-5,-2)\), \((1,3)\), \((4,\infty)\)
