Question

Which graph represents the equation y2=-4x?

Answer 1

The answer is A

Explanation:

Its just the other persons longer answer but simplified I guess..

Answer 2

See attachment.

Explanation:

The given equation is

`{y}^(2) = - 4x`

We solve for x to obtain:

`x = - (1)/(4) {y}^(2)`

This is a horizontal parabola that has its vertex at the origin.

The graph of this parabola opens in the direction of the negative x-axis because of the negative coefficient.

The focus is (-1,0) and the directrix is x=1
