Question

I have a graphing questionwill attach a photo but I just need to know the intervals showing the largest increase in decrease in the algebraic terms

Answer 1

To solve this question we need to identify the intervals where there is the biggest increase and decrease on this function. If we call the year by the unkown variable x, then the intervals are:

Biggest increase: 1970 < x < 1975

Biggest decrease: 1985 < x <1990
