Question

where is the decreasing? (+∞, -6.25) ∪ (36, -6.25) (-∞, ∞) (-∞, -2.55) ∪ (0, 2.55) (-∞, 0)

Explanation:

Step1: Recall the definition of a decreasing function

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: Analyze the graph

Looking at the graph, we observe the intervals where the function is going down as we move from left - to - right.

Step3: Identify the correct interval

By visual inspection of the graph (assuming standard coordinate axes), we can see that the function is decreasing on \((-\infty,-2.55)\cup(0,2.55)\).

Answer:

\((-\infty,-2.55)\cup(0,2.55)\)
