The parabola y = −(x − 3)2 + 4 is graphed below. Use four trapezoids of equal width to approximate the area under the parabola for 1 ≤ x ≤ 5. Is this area an over or an under estimate of the true area under the parabola? Explore this using the Estimating Area Under a Curve eTool (Desmos). Homework Help ✎
