Carefully graph the function

. 1-125 eTool (Desmos) Homework Help ✎ Iveta wants to find

*A*(*f*(*x*), −1 ≤*x*≤ 5), so she decided to split the region into 10 trapezoids and approximate the area. Explain to Iveta why this is not the most efficient method.Calculate

*A*(*f*(*x*), −1 ≤*x*≤ 5).

Can you find a way to calculate the area accurately with less than 10 trapezoids?

Because the function is composed of two linear pieces, the exact area can be computed using two trapezoids.
