Consider the left and right Riemann sums that would approximate the area under y is equal to g of x between x equals two and x equals eight. So we want to approximate this light blue area right over here. Are the approximations overestimations or underestimations? So let's just think about each of them. Let's consider the left and the right Riemann sums. So first the left, and I'm just gonna write left for short, but I'm talking about the left Riemann sum. So they don't tell us how many subdivisions to make for our approximation, so that's up to us to decide.
