And then let me try to graph v of t. So once again, if this is my y-axis, this is my t-axis. And I'm going to graph y is equal to v of t. And if this really is a parabola, then the slope over here is 0. The slope, the rate of change is 0. And then it keeps increasing. The slope gets steeper and steeper and steeper. And so v of t might look something like this. So this is the graph of y is equal to v of t. Now, using this graph, let's think if we can conceptualize the distance or the change in position between time a and between time b.
