 $x=-\frac{b}{2a}$  

 $x=\frac{\left(p+q\right)}{2}$  

 $x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$  

 $x=h$  

the y-intercept

the y-value of the vertex

the x-value of the vertex

the x-intercepts

Vertex:  $\left(\frac{5}{2},\ 3\right)$  

Vertex:  $\left(-\frac{5}{2},\ -97\right)$  

AOS:  $x\ =\ \frac{5}{2}$  

AOS:  $x\ =\ -\frac{5}{2}$  

y-intercept:  $\left(0,\ 3\right)$  

 $y=2x^2+8x-5$  

 $y=2x^2-8x-5$  

 $y=-2x^2+8x-5$  

 $y=2x^2+8x+5$
