You can put this solution on YOUR website! For the function given by f(x)= 2x^2 - 12x + 23. First find the vertex and the axis of symmetry, then graph the function
-------------------
Put in vertex form by completing the square:
f(x)= 2x^2 - 12x + 23
Rearrange:
2x^2 - 12x = y-23
2(x^2 - 6x + ?) = y-23 + 2?
2(x^2-6x+9) = y-23+18
2(x-3)^2 = y-5
---
Vertex: (3,5)
Axis of symmetry: x = 3
