Question

What is the direction of the opening of the parabola `x=-2y^2`?

Answer 1

`x=-2y^2` opens to the left (in the direction of the negative X-axis)

Explanation:

Assuming a standard Cartesian plane layout; negative, x values with increasing magnitude will appear further to the left with their increase in magnitude.
