This week in precalc 11 we had review for our unit test and then we relearned graphs after that. We also learned about the parabola. A parabola is a U shaped curve on a graph that is symmetrical on either side. when we look at that graph we should be able to find the vertex, line of symmetry, x-intercept, y-intercept, domain and range. I found that when we first worked on the graphing that it was decently easy but when we progress it becomes more difficult (as always).  One thing to note is that the vertex is one of the most important pieces of information and it can be the highest point on the graph or the lowest (min, max).
