The interval at which a function increases, is the interval where the output values of the function increase with the input value
The intervals at which the function of the attached graph increases are: [tex](-\infty, -2)\ u\ (2,\infty)[/tex]
The graph is not given; so, I will explain this question with the attached graph
From the attached graph, we have the following observations:
- As x increases from [tex]-\infty[/tex] to -2, the value of function increases from 0 to 16.
- As x increases from 2 to [tex]\infty[/tex], the value of function increases from -16 to 0.
So, the intervals at which the function increases are: [tex](-\infty, -2)\ u\ (2,\infty)[/tex]
