January 30th, 2017

2. Standard Form ***Recall: 1) Vertex is _________.
2) Axis of symmetry is _______.
3) Y-intercept is ______.
4) X-intercepts are found by setting _____.
5) Opens upward if ________ and downward if ________.

3. Ex. 1: Sketch a graph for each of the following quadratic functions by finding the vertex, axis of symmetry, y-intercept, and x-intercepts (if any). State whether the vertex is the minimum or maximum point on the graph and explain your reasoning. a) b)

4. Ex. 2: Create the equation of each quadratic function described below
Ex. 2: Create the equation of each quadratic function described below.with a vertex of
With a vertex of (3, -1) and a y-intercept of -4.
b) With a vertex of (-2, -3) and a y-intercept of 7.
(*Hint: Consider which form of the quadratic function will make this the easiest to plug in this information: standard, vertex, or factored.)
