Question

consider the given piecewise function. Select the section(s) of the graph where the function is decreasing. Select all the correct locations on the graph. NO LINKS! ​

Answer 1

Step-by-step explanation:

The function is decreasing when f(x) decreases as x increases.

We can observe one section that is increasing, it is when:

• 0 ≤ x ≤ 3 (the black section)

So excluding this section, the decreasing sections are:

• blue, red and green sections

or, when x is:

• x ∈ (- ∞, 0) ∪ (3, + ∞)
