if s(t)=2t+3t+4, what is the instantaneous velocity at t=2?
answer the instantaneous velocity at t=2 is the first derivative at t=2.
S'4t+3, let t=2 you get 11
i'm new to calculus and i don't understand how s' is 4t3. can someone explain the thought process to me please. i thought the answer would be 8+6+4
