Assume that each of the follwing functions gives the position of an object at time t. Find the velocities indicated by setting up and evaluating a limt algebraically.

(a) s(t) = 3t^2, Find v(-1).

(b) s(t) = 1/t , Find v(2).

(c) s(t) = square root of t, Find v(1).

The answers that I got were the following...

a)3

b)1/2

c)1

I did them another way and the answers I got were

a)-6

b) -(1/4)

c) I didn't really get any answers here.

Please tell me which answers are right or if any of them are right...
