V of T is equal to T, T plus negative 6, or T minus 6. We can verify that. The derivative of this with respect to time is just 1, and when time is equal to 3, 3 minus 6 is indeed negative 3. We've been able to figure out velocity as a function of time. Now let's do a similar thing to figure out position as a function of time. We know that position is going to be an antiderivative of the velocity function. Let's write that down.
