URGENT! 20 POINTS!!! Use the given information to write an equation of each parabola.
The parabola has focus (-8.0) and vertex at the origin

Step-by-step explanation:

use y^2=4px

p is the distance from the vertex to the focus, which is 8 units left

y^2=4(-8)x

y^2=-32x

Use y²=4px  where p is the distance from the vertex to the focus,

p = 8 to the left,

so p = -8

Plug that in:

y² = 4(-8)x

Sole / simplify / multiply:

y² = -32x

step-by-step explanation:

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
