What is the standard equation of the parabola with vertex
 

 $\left(2,-4\right)\ and\ focus\ \left(-1,-4\right)?$  

•  $\left(y+4\right)^2=-12\left(x-2\right)$  

•  $\left(y+4\right)^2=12\left(x-2\right)$  

•  $\left(x-2\right)^2=12\left(y+4\right)$

What is the standard equation of the parabola with vertex  $focus\left(11,7\right)\ and\ directrix\ x=1?$  
 

•  $\left(y-7\right)^2=20\left(x-6\right)$  

•  $\left(y-7\right)^2=-20\left(x-6\right)$  

•  $\left(x-6\right)^2=20\left(y-11\right)$  

•  $\left(x-6\right)^2=-20\left(y-11\right)$

Based on the graph, what is the standard equation of the parabola?

• $\left(y+4\right)^2=12\left(x-2\right)$

• $\left(y+4\right)^2=-12\left(x-2\right)$

• $\left(x-2\right)^2=12\left(y+4\right)$

• $\left(x-2\right)^2=-12\left(y+4\right)$

True or False?
When the y-part is squared, the parabola opens up or down.

• True
• False
