What is an equation of a parabola with the given focus?
Focus: (-2,0)
Can you write the steps out to help me? This was all the information I was given

Answer 1

The answer to your question is y² = -8x

Explanation:

The equation of a horizontal parabola with vertex (0, 0) is: y ² = -4px

and p is the distance from the vertex to the focus, in this problem

p = 2.

Substitution

y² = -4(2)x

Simplification

y² = -8x
