Question

(1 point) the equation for a parabola has the form y=ax2+bx+cy=ax2+bx+c, where aa, bb, and cc are constants and a≠0a≠0. find an equation for the parabola that passes through the points (−1,−10)(−1,−10), (−3,−8)(−3,−8), and (−4,−1)(−4,−1).

Answer 1

A graphing calculator working the quadratic regression problem for these three points gives the equation as

y = 2x² +7x -5
