a) The rectangles in the graph below illustrate a left endpoint Riemann sum for $f(x) = \frac{x^2}{10}$ on the interval $[4, 8]$. The value of this Riemann sum is 16.15 and this Riemann sum is an underestimate of the area of the region enclosed by $y = f(x)$, the x-axis, and the vertical lines $x = 4$ and $x = 8$.
