Which of the following could be the equation for a parabola that opens to the left with vertex (-17,2)?
Sholpan [36]
A sideways opening parabola is in the form x= y^{2}, so we know from the process of elimination that it will either be b or c.  Next we have to realize that if the parabola opens to the left it is a negative parabola, just like if a parabola opens upside down it is a negative parabola.  So the one that has the negative out front is b.
