randRangeNonZero( -3, 3 ) randRangeNonZero( -5, 5 ) randRangeNonZero( -5, 5 )

Adjust the leading coefficient and vertex coordinates to make the blue parabola match the orange parabola.

How do these numbers affect the shape and position of a parabola?

graphInit({ range: 10, scale: 20, tickStep: 1, axisArrows: "<->" }); // Plot the orange parabola style({ stroke: "#FFA500", fill: "none", clipRect:[[-10, -10], [20, 20]], arrows: null }); plot(new Parabola(A, X1, Y1).graphieFunction, [-10, 10]); style({ stroke: "#6495ED", strokeWidth: 3, fill: "none", clipRect:[[-10, -10], [20, 20]], arrows: null }); graph.currParabola = new Parabola(1, 0, 0); graph.currParabola.plot();

`y - 0 = 1(x - 0)^{2}`

[A, X1, Y1]
var parab = graph.currParabola; return parab.getLeadingCoefficient() === A && parab.getVertexX() === X1 && parab.getVertexY() === Y1;
guess = guess.length ? guess : [1, 0, 0]; var parab = graph.currParabola; parab.update.apply(parab, guess); redrawParabola(false);
guess = guess.length ? guess : [1, 0, 0]; var a = guess[0], x = guess[1], y = guess[2]; var equation = "y - " + y + "=" + a + "(x - " + x + ")^{2}"; equation = cleanMath(equation); $("#equation-label").html("<code>" + equation + "</code>").tex();
