alg 2 sec. 5.1 and 5.2 outline notes.notebook September 25, 2012 Tonight's Homework: Pages 6 9 #19, 23, 27, 33, 37, 44 46, 55, 57 Pages 15 – 17 #9, 11, 17, 27, 29, 37, 39, 51, 53 Sec. 1.1 Graph Quadratic Functions in Standard Form *Graph *Finding the min or max value *Multistep problem Sec. 1.2 Graph Quadratic Functions in Vertex or Intercept Form *Graph *Using a model *Changing the form of the equation Standard Form: f(x) = ax 2 + bx + c Direction: a > 0 _______________ a < 0 _____________ The Axis of Symmetry is The vertex is The yintercept is c. So, the point is (0, c) is on the parabola. Compared to the graph of f(x) = x 2 , a graph is narrower if |a| > 1 and wider i y=x 2 Parent Function: y=2x 2 y= 1 x 2 2 y=x 2 |a| < 1wide |a| > 1narrow |a| = 1same widths: Compare the graphs. (wider, narrower, same) 1) f(x) = Graph, label the vertex, and axis of symmetry.
