## I need help with this Problem..

Question Is
Suppose B(t) gives the amount of weight (in pounds) that Jesse Bench presses at time t (in weeks). Suppose we know that B'(20)=212 and B'(20)= -7. Assume B9t) is a differentiable (and hence also continuous) function.
a) Approximate JEsse's Bench Weight at week 19.
b) Approximate his bench weight at week 21.
