WebSo our vertex right here is x is equal to 2. Actually, let's say each of these units are 2. So this is 2, 4, 6, 8, 10, 12, 14, 16. So my vertex is here. That is the absolute maximum point for this parabola. And its axis of symmetry is going to be along the line x is equal to 2, along the vertical line x is equal to 2. WebSo the desired quadratic is: y = 3 ( x2 − 7) = 3 x2 − 21 You can use the Mathway widget below to practice finding the quadratic equation from its solutions.

WebDec 2, 2024 · Steps. 1. Start with the standard form of a general quadratic equation. While any equation with an term in it qualifies as quadratic, the standard form sets everything to 0. Remember that are coefficients that can be any real number, so don't substitute any numbers in for them - we want to work with the general form. WebThe reason this works is that points on a vertical line share the same x-value (input) and if the vertical line crosses more than one point on the graph, then the same input value has 2 different output values (y-values) on the graph. So, it fails the definition of a function where each input can have only one ouput. ( 7 votes) Turtle Man Travis
