Let

*f*(*x*) =*x*^{3}+ 2 and let*g*(*x*) = 2*f*(*x*). Try this using the 2-169 eTool (Desmos). Homework Help ✎Write out the function

*g*(*x*).Draw a graph of

*f*(*x*) and*g*(*x*) for the interval [−2, 1].Use your program to compare the areas under each of the curves separately. What do you conclude?
