In this article, we review how to graph quadratic functions.
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. ( 5 votes) Smriti 6 years ago
