Pls help

Work through the following steps to evaluate (2 2 + 8x + 6) do. a ) We know that a = 2 " and b = CO b) Using n subintervals, Ax = c) Assume that the sample points in each interval are right endpoints. Find the following sample points: 1 = + - 2 - 3 = 2+ In general, the ith sample point is ci = 2+ 42 n V Note: your answer will be an expression in terms of i and n. d) Now find the sum of the areas of n approximationg rectangles. Note: your answer will be an expression in terms of n. f(xi ) Ax = 20 + 1+1 2+1 X i=1 32 (n + 1) (2n + 1) + 962 + 1 + 104 &
