This week we worked on converting from standard for to vertex form by completing the square.

Ex: y=x²+4x-5

y= (x²+4x+4)-5-4

y=(x+2)²-9

This week, we focused on analyzing quadratic functions and changing them to parabola’s.

Identifying the y intercept of the graph of a quadratic function.

y= 3-14x+5x²

y= 3-14(0)+5(0)²

y=3-0+0

y=3
