Thank you :) **Title: Approximating the Area Under a Curve Using Lower and Upper Sums****Objective:**Learn how to approximate the area under the graph of the function \( f(x) = 5x^3 \) from \( x = 3 \) to \( x = 11 \) using lower and upper sums with \( n = 4 \) and \( n = 8 \) subintervals.**Instructions:**Use symbolic notation and fractions where needed to calculate the following:**(a) Lower Sums (\(s_n\)):**Compute the area using rectangles that lie below the graph of \( f(x) \).- **For \( n = 4 \) subintervals:** - Lower sum \( s_4 = \) [Enter Answer Here]- **For \( n = 8 \) subintervals:** - Lower sum \( s_8 = \) [Enter Answer Here]**(b) Upper Sums (\(S_n\)):**Compute the area using rectangles that lie above the graph of \( f(x) \).- **For \( n = 4 \) subintervals:** - Upper sum \( S_4 = \) [Enter Answer Here]- **For \( n = 8 \) subintervals:** - Upper sum \( S_8 = \) [Enter Answer Here]This exercise helps understand the concept of Riemann sums and the method of approximating integrals by dividing the area under a curve into a series of rectangles. (b) By using upper sums \( S_n \) (rectangles that lie above the graph of \( f(x) \)).- upper sum \( S_4 = \) [text box]- upper sum \( S_8 = \) [text box]
