Question

does this equation open left or right? x=1/4y^2

Answer 1

I am confused b/c the question is basically the equation of a horizontal parabola

Answer 2

Yes, which way are the arrows pointing to is the question.

Answer 3

so "p" = 1 making it greater than 0 so it must be going right?

Answer 4

Well, just think about this:

On a y=x^2 graph, it opens up.
On a y=-x^2 graph, it opens down.

You have x=y^2 here. Which side is going in the positive direction? The right.

So you are correct but you don't have to play with numbers necessarily. This is easier as well.
