Use the trapezoid rule to estimate the area under the graph of y = x2 + 2 for values of x from 0 to 3.

So basically you form little trapaziods to fin =d the area. It's been a long time since I took calculus so Imma have to improvise

Area or trapaziod = area of rectangle + area of triangle so you get
2*1+(3-2)*1/2+3*1+(6-3)*1/2+6*1+(11-6)*1/2=15.5

What is the question that you needed answered?
