WebQuadratic equations are written in vertex form as: y=a (x-h)^2+k. where (h,k) represent the vertex of the parabola, and the sign of a represents if the graph of parabola is open upwards or downwards. In your equation y = - (x-2)^2+3, Vertex (h,k)= (2,-3) Since a=-1, this tells us that the graph will be open downwards. WebDec 26, 2014 · Dec 26, 2014. When you graph a quadratic, there are a couple of things you need to consider that will make your life easier. Firstly, you need to find the vertex . This is derived through (wait for it) vertex form. In the equation y = a(x −h)2 + k, the point (h,k) is your vertex. It is either the highest or lowest point on your graph, and it ...
