4. For the function below, sketch a graph of the function, and then find the smallest possible value and the largest possible value for a Riemann sum of the function on the given interval as instructed.
Solution:
Smallest possible value = f(3)*1 + f(4)*1 + f(5)*1+f(6)*1 = 9*1+16*1+25*1+36*1 = 86
Largest possible value = f(4)*1 + f(5)*1+f(6)*1 + ...
