Find quadratic equation from 2 points
WebA quadratic equation (also referred to as a quadratic function) is a polynomial whose highest exponent is 2. The standard form of a quadratic equation looks like this: f (x) = ax² + bx + c When graphed on a coordinate plane, a quadratic equation creates a parabola, which is a u-shaped curve. Web1 Answer Sorted by: 4 Plug in ( x, y) = ( 18, 13.6) to get 13.6 = a ( 18 − 12) 2 + 16 and then solve for a. You can do this because you know the point ( 18, 13.6) is on the parabola, so it must satisfy the equation.

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). WebOne common method of solving quadratic equations involves expanding the equation into the form ax2 +bx+c =0 a x 2 + b x + c = 0 and substituting the a a, b b and c c …
