Area
The function displays the rate at which the snow melt is changing (cm per day). By our definition, the area between the function and the x-axis is the total accumulation of snow melt.
Estimate the area of the region beneath the function between May 10th (day 40) and June 9 (day 70) using the formula for area of a trapezoid. The bases are the parallel sides of the shaded quadrilateral.
