vertical lines x=-1 and x=0,
www n
i) find upper sum approximation using 4 subintervals of equal size.
ii) find lower sum approximation using 4 subintervals of equal size.
iii) find the area.
S = -1, t = 0, u = -7
Hint: The figure of the function f(x) = (x- s)(x-t)(x-u) can be drawn as follows, where s<t<u . The
location of the y-axis is changed according to the values of s,t,u .
