  11. Evaluate the function when x = -1 and x = 3.

  12. Evaluate the function when x = -1 and x = 3.

  13. Graphing

  14. 4.6 Continued: Graphing Contains (0, 0) If a is positive: V-shape opens up. If a is negative: V-shape opens down. If : V-shape is narrower than If : V-shape is wider than

  15. Determine if the graph opens up or down and if it is narrower or wider than .

  16. Graphing Steps 1.) Plot (0, 0) 2.) Use a as a “slope” and plot additional points to the right. 3.) Using symmetry, find the matching points on the left to get a V-shape.
