Answer 3

General rule:

y = a(x-h)²+k opens up for a > 0, and down for a < 0.

x = a(y-k)²+h opens right for a > 0, and left for a < 0.

Using this rule, your equation opens right.

Answer 4

This is a parabola of the form x = Ay², where A is any real number except 0. If A is positive (3 in this case), the parabola opens to the right. If it is negative, it opens to the left.

This one opens to the right.

Answer 5

It opens to the right because as y approaches +/- infinity, x approaches +infinity.
