Answer:
The equation of the parabola which opens left or right is
.
Step-by-step explanation:
We know that,
If in the equation of the parabola,
<em>1. If x is squared, then the parabola opens upwards or downwards.</em>
<em>2. If y is squared, then the parabola opens towards left or right.</em>
Since, we want the equation of the parabola which opens left or right.
So, we get that,
The variable 'y' is being squared in the equation of the given parabola (from 1).
<h3>Thus, the equation of the parabola which opens left or right is

.</h3>
