(IMPORTANT) Please answer B,C, and D
The graph of ff(xx) = 8 − xx3 and the line l which is tangent to ff aaaa xx = 1 is shown in
the figure below. The equation for line l is yy = −3xx + 10. Region R is the shaded
region between line l, the graph of ff and the y-axis while S is the shaded region
between line l, the graph of f and the x-axis.
