Method 2: Graphing Parabolas using Mapping Notation
khxay 2
Mapping Notation: ,, yx
Practice: State the mapping notation for the following parabolas:
a) y = 3x2 - 5 b) y = -(x + 7)2 c) y = -2x2 + 4
d) y = ½ (x – 6)2 + 1 e) y = 5(x + 1)2 - 9 f) y = – ¼ (x – 3)2 + 5
How to graph using Mapping Notation 1) List at least 5 key points from your parent relation. (Make sure you include – and + ‘x’ values. 2) Using mapping notation, find out the new coordinates of these key points. 3) Plot the new points, then draw your parabola.
