Finding a quadratic equation from 3 points
WebI want to construct a quadratic equation P ( x), that passes through these three points. My lecturer used the following steps: The quadratic equation is: P ( x) = A ( x − x 2) 2 + B ( x − x 2) + C So we start by solving the equations: f ( x 0) = A ( x 0 − x 2) 2 + B ( x 0 − x 2) + C f ( x 1) = A ( x 1 − x 2) 2 + B ( x 1 − x 2) + C f ( x 2) = C WebMay 17, 2011 · We know that a quadratic equation will be in the form: y = ax 2 + bx + c. Our job is to find the values of a, b and c after first observing the graph. Sometimes it is easy …
