We saw how we could fairly easily create the graph from the factored form and easily found the x-intercepts. Then we found the axis of symmetry by averaging the x-intercepts. Then we used that value to determine the vertex. We used the "a" value to determine another 2 quick points on the graph. We were reminded that a y-intercept can be found by letting x = 0.
