The position of a particle at time t is given by s(t)=t^2+2t+1.

a) compute the average velocity from time 2 to time 3.

b) compute the average velocity from time 2 to time 2.5.

c) compute the average velocity from time 2 to time 2.01.

d) give and expression for the average velocity from time 2 to time t.

Need to know how you got that answer, thanks!
