By using finite approximation to estimate the area under the graph of the function using a lower sum with two rectangles of equal width of the function f(x)=x^2 in the interval [0,1] will be? Answer: 0.125

Dividing [0,1] into two equal subintervals and taking the lower (left) function values yields A=∑f(xi​)Δx=0.5(0+0.25)=0.125.
