Find quadratic equation from 2 points
WebTo finish our graph, we need to find another point on the curve. Let's plug x=-4 x = −4 into the equation. \begin {aligned} y&=-2 (-4+5)^2+4\\\\ &=-2 (1)^2+4\\\\ &=-2+4\\\\ &=2 \end {aligned} y = −2(−4 + 5)2 + 4 = −2(1)2 + 4 = −2 + 4 = 2 Therefore, another point on the parabola is (-4,2) (−4,2). http://www.solving-math-problems.com/quadratic-equation-passing-through-two-points.html
