Write the summation to estimate the area under the curve y = 2x2 + 1 from x = 0 to x = 4 using 4 rectangles and left endpoints. the summation from i equals 0 to 4 of the quantity 2 times i squared plus 1 the summation from i equals 1 to 3 of the quantity 2 times i squared plus 1 the summation from i equals 0 to 3 of the quantity 2 times i squared plus 1 the summation from i equals 1 to 4 of the quantity 2 times i squared plus 1

The correct option is C.

Step-by-step explanation:

The given equation of curve is

We need to find the area under the given curve from x = 0 to x = 4 using 4 rectangles and left endpoints.

We have 4 rectangles in x = 0 to x = 4. So,

Left Riemann sum:

Using Left Riemann sum, we get

The area under the given curve from x = 0 to x = 4 using 4 rectangles and left endpoints is

Therefore the correct option is C.
