Graphing quadratics in standard form

Graphing quadratics in standard form. Standard Form ax 2 + bx + c. To graph: Find the vertex The x-coordinate of the vertex is at Plug this x value into equation to find y Graph the vertex Use a as the slope to move from vertex. Example 1 : Graph y=2x 2 -8x+6.

  1. Graphing quadratics in standard form

  2. Standard Form ax2 + bx + c • To graph: • Find the vertex • The x-coordinate of the vertex is at • Plug this x value into equation to find y • Graph the vertex • Use a as the slope to move from vertex

  3. Example 1: Graph y=2x2-8x+6 • Start table at x=2 and find values on either side • Vertex: use b=-8 and a=2 x=2

  4. y=-x2+2x+5
