Let K(t) denote the capital stock of an economy at time t. Then net investment at time t, denoted by l(t), is given by the rate of increase of K(t). a) If l(t)= 3t2+2t+5 (t20) , what is the total increase in the capital stock during the interval from t=0 to t=5?

Is that supposed to be

I(t) = 3t^2 + 2t + 5

? What does that (t20) mean at the end??
