Question

Hi can you help me to solve the equation, please! Additional information. This question has two parts. The second part that is B . Is about if the interval where the function is decreasing !

Answer 1

Let's determine at which interval of the given graph is the function increasing.

From the given graph, the following are the interval where the function is increasing.

Interval 1: (-8, -2)

Interval 2: (0, 2)

Interval 3: (5, ∞)

Therefore, the answer is Choice D:

`INCREASING\colon(-8,-2\text{ ) }\cup\text{ (0, 2) }\cup\text{ (5, }\infty)`

The rest of the parts that weren't named are the parts where the graph is decreasing. These intervals are:

Interval 1: (-∞, -8)

Interval 2: (-2, 0)

Interval 3: (2, 5)

Therefore, the answer is Choice C:

`DECREASING\colon\mleft(-\infty,-8\mright)\text{ }\cup\text{ }\mleft(-2,0\mright)\text{ }\cup\text{ }\mleft(2,5\mright)`
