In which direction will this parabola open? x= 3(y-5)^2-7

Question

i dont understand which way it would open! /;

Answer 1

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 2

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 3

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