How to Make a Quadratic Equation From a Graph
To form a quadratic equation from a graph, first identify the key points like the vertex and the x-intercepts (if they exist). With these, you can write the equation in vertex form or factored form. Then, use any additional points on the graph to solve for coefficients.

Easy-peasy! Find the vertex, get the x-intercepts, and plug them into the vertex or intercept form of a quadratic equation. Voil脿!
Just grab three points from the graph that aren't in a straight line, and solve for a, b, and c in the standard form ax虏 + bx + c.
I once made a quadratic equation by finding the vertex and two points. With a bit of algebra, I cracked it like a code.
