The vertex of this parabola is at (-4, -1). when the y-value is 0, the x-value is 2. what is the coefficient of the squared term in the parabola's equation?

This is a parabola in vertex form,

a is the coefficient on y^2 we seek.  Since it's sideways we have p=-1, q=-4

When y=0,

A

Option A

Step-by-step explanation:

The shape of the vertex of a parabola is:

Where the point (k, h) is the vertex of the parabola and "a"  is the coefficient of the squared term.

In this case we know that the vertex of this parabola is:

(-4, -1)

Then:

and

So the equation is:

We know that whe the y-value is 0, the x-value is 2.

This mean  that:

the 3rd option is right

step-by-step explanation:

no because after the troops were pulled many blacks were killed by hangings lynchings and other cruel ways which in a way interrupted the reconstruction of the south and differed from the way abraham lincoln had an idea of reconstruction
