Which is an expression for the midpoint Riemann sum?

• 2⋅f(0)+2⋅f(2)+2⋅f(4)+2⋅f(6)
• 2⋅f(2)+2⋅f(4)+2⋅f(6)+2⋅f(8)

Approximate the area between the x-axis and g(x), from x = 10 to x = 16 using a LEFT Riemann sum with 3 unequal subdivisions.

• 10 units²
• 15 units²

• Overestimate
• Underestimate
• Neither
• Both
