1. a) When you are given the vertex form of a quadratic relation such as y=2(x-1)- 3, express the equation in the standard form. b) Put the vertex and the standard form of the quadratic relation into "Desmos" and prove that the two relations are the same parabola. Take a screenshot of the graph and equations and include in the dropbox submission. 21. a) When you are given the vertex form of a quadratic relation such as y= -2(x+3)+5, express the equation in the standard form. b) Put the vertex and the standard form of the quadratic relation into "Desmos" and prove that the two relations are the same parabola.
