So, the way to think about it is creating a tangent line that just touches
the point. If we know the slope of the tangent line, then we could say
that that is the instantaneous rate of change at that point. Also, since
slope is velocity in this case, if we talk about velocity right at the time x, it
is the instantaneous rate.

different y value for the values of x. Let's find out the instantaneous
