Homework Statement
I have the following points that were gathered from a displacement vs. time graph (the graph is of a ball being dropped from rest). The line is parabolic. The quadratic regression for the points is [tex]-4.03x^2-2.06x+1.20[/tex] where [tex]R^2=0.99857[/tex].
Correct me if I'm wrong but the quadratic regression is the same as this: [tex]h(t)= \frac {1}{2}At^2+V_{0}t+h_{0}[/tex]
I need to make a velocity vs. time graph with this information but I need a little guidance.

The Attempt at a Solution
I performed the quadratic regression but now I'm stuck
