Step 1
- Delta x = (5 - 1) / 2 = 2 - Right-hand side points: x = 3, x = 5 - Height at x = 3: f(3) = 22 + 1(3) = 25 - Height at x = 5: f(5) = 22 + 1(5) = 27 - Area of first rectangle = 2 * 25 = 50 - Area of second rectangle = 2 * 27 = 54 - Total area ≈ 50 + 54 = 104 Show more…

Use a Riemann sum to approximate the area under the graph of $f(x)$ on the given interval, with selected points as specified. $f(x)=x^{2} ;-2 \leq x \leq 2, n=4,$ midpoints of subintervals
