To draw a quadratic graph from its equation, Set up or complete a table with values of \(x\) Substitute each value of \(x\) into the equation to find each corresponding value of \(y\) ...

This means that the (0.0506) in front of x 2 in the quadratic fit must be equal to the (1/2)a term in the kinematic equation giving an acceleration of 0.1012 m/s 2.
