The graph of a quadratic function is a parabola The parabola can either be in "legs up" or "legs down" orientation We know that a quadratic equation will be in the form y = ax 2 bx c Our job is to find the values of a, b and c after first observing the graph Which of the following equations will be the graph of a parabola?A quadratic equation as you remember is an equation that can be written on the standard form a x 2 b x c = 0, w h e r e a ≠ 0 You know by now how to solve a quadratic equation using factoring Another way of solving a quadratic equation is to solve it graphically The roots of a quadratic equation are the xintercepts of the graph

Trey graphs the equations y=-x^2+2x+3
Trey graphs the equations y=-x^2+2x+3-Right over here I have the graph of f of X and what I want to think about in this video is whether we could have sketched this graph just by looking at the definition of our function which is defined as a rational as a rational expression we have 2x plus 10 over 5x minus 15 so there's a couple of ways to do this first you might just want to pick out any numbers that are really easy toGraphing these points and connecting them with a straight line give us the graph of 2x y = 6 If the graph intersects the axes at or near the origin, the intercept method is not satisfactory We must then graph an ordered pair that is a solution of the equation and whose graph is not the origin or is not too close to the origin
