on 2 August 2011#### Transcript of Introduction to Parabolas

Parabolas symmetric equation is always

x= at the VERTEX of the parabola where the parabola changes DIRECTION axis of symmetry

(line of symmetry) Graphing Solving Defining minimum maximum vertex is lowest point on the parabola vertex is the highest point on the parabola Follow the

Order of Operations when a is positive when a is negative but backwards y = ax² y = x² y = -2x² Examples x² = 256 x = 16 or -16 Don't forget to

CHECK! 3(2n - 11)²=75 (2n - 11)² = 25 2n - 11 = 5 or 2n - 11 = -5 2n = 16 or 2n = 6 n = 8 or n = 3 2x² = 32 x² = 16 x = 4 or -4
