Ireally need on this : ,( 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 parabolas equation? a. 6 b.-6 c. -3 d.3

The equation of parabola is

Where vertex is (h,k) .

And it is given that (h,k) =(-4,-1) and when x=2, y=0.

So we get

So the equation of the parabola is

And the coefficient of square term is 6 here.

So the correct option is 6 .

yes

step-by-step explanation:

they have to be opposite and reciprocal of eachother.

  answer:

  write 548 as 500 + 40 + 8. multiply each addend by 5. then add the three products to get 2,740.
