5.Find (f+g)(8) and (fg)(−2) where g(x) is the piecewise function from 4 and f(x) =3×2−6.
3.a Find the AROC of g(x) = 5x−3 from x= 1 tox= 5 I solved this and got 5
3.b Estimate f(3) using the AROC or average rate of change. Is the estimate equal to f(3)? If it is, why do you think it is in this case, but not in others?
