The graph of a quadratic equation in two variables (y = ax 2 bx c) is called a parabola Furthermore, how do you find the Y intercept of ax 2 bx c? It would be worth your while to learn another standard form of the equation of a parabola, and you can complete the square, given $y = ax^2 bx c$, to obtain this form $$4p(y k) = (xh)^2$$ The vertex of the parabola is given by $(h, k)$ $$h = \frac{b}{2a};\quad k = \frac{4ac b^2}{4a}$$The Graph of y = ax2 bx c 393 Lesson 64 The Graph of y = ax2 bx c Lesson 6–4 2 BIG IDEA The graph of y = ax bx c, a ≠ 0, is a parabola that opens upward if a > 0 and downward if a < 0 Standard Form for the Equation of a Parabola Homer King hits a high–fl y

Y=ax^2 parabola-Find the yintercept for the equation by letting x equal zero The equation becomes y = 0x squared 0x c or y = c Note that the yintercept of a quadratic equation written in the form y = axIn the next few questions, we will find the roots of the general equation y = a x 2 b x with a ≠ 0 by factoring, and use that to get a formula for the axis of symmetry of any equation in that form Question 5 We want to factor a x 2 b x Because both terms contain an x,
First complete the square to get the form y = a(x − h)2 k where again a ≠ 0 Then show that this is also the equation for the parabola with its focus at the point (h, k 1 4a) and directrix at the horizontal line y = k − 1 4a These are welldefined since a ≠ 0 and clearly the focus is not on the directrix Given the Equation #color(red)(y=f(x)=4x^2# A Quadratic Equation takes the form #color(blue)(y=ax^2bxc# Graph of a quadratic function forms a Parabola The coefficient of the #color(red)(x^2# term (a) makes the parabola wider or narrow If the coefficient of the #color(red)(x^2,# term (a) is negative then the parabola opens down The term Vertex is usedI mean, given the focus x, y and directrix (I'll use a horizontal line for simplicity) y = k you can find the equation of the quadratic;
