The correct answer is d but i don’t understand

The length of the base of the rectangle is 1.5-1=0.5

We need to find the height. The height is equal to y-value of the point that lies in the corner of the rectangle and also on the graph of the function. We put the x-value of that point into the function. So ,the height is equal to

Therefore, the area of the rectangle is

Exponential: 64

Linear: 17
