Question

I keep getting the wring answer. Can you help?Identify the intervals where the graph is increasing and decreasing. Answer in interval notion.

Answer 1

Consider that function increases when the value of the dependent variable increases as values of the independent variable increases. Furthermore, function decreases when the values of the dependent value decreases as the values of the independent variable increases.

Then, by considering the previous description you have:

Interval where the graph increases:

(1,∞)

Interval where the graph decreases:

(-∞,1)
