In this part you do not have to sketch the graph and you may even be given the sketch of the graph to start with. This form of the equation for a quadratic function is called vertex form because we can easily read the vertex of the parabola. We know that the point 56 is on the graph which means that if we substitute x 5 into the graphs equation we will get a y-value of 6.
The standard form of a quadratic equation is 0 a x 2 b x c where a b and c are all real numbers and a 0.
We know that the point 56 is on the graph which means that if we substitute x 5 into the graphs equation we will get a y-value of 6. The graph of a quadratic function is a parabola. Change a Change the Graph Another form of the quadratic function is y ax2 c where a 0 In the parent function y x2 a 1 because the coefficient of x is 1. Powered by x y a 2 a b 7 8.
