Riemann Sum 2
Use a Riemann sum to approximate the area under the graph of f(x) on the given interval with the selected points as specified.

f(x) = x^3, 1 x ≤ 3, n = 5, Left-hand Rectangle Approximation Method

$\int_a^b f(x) \, dx \approx \frac{b-a}{n}\left[f(x_0) + f(x_1) + f(x_2) + ... + f(x_{n-1})\right]$
