So acceleration as a function of time is just going to be the first derivative of velocity with respect to time, which is equal to the second derivative of position with respect to time. It's just going to be the derivative of this expression. So once again, using the power rule here, that's going to be six t, and then using the power rule here minus six, and once again, we will restrict the domain. And we can graph that as well. And we would see right over here, this is y is equal to acceleration as a function of time. And you can see at time equals zero, our acceleration is quite negative, it is negative six. And then it becomes less and less and less negative.
