Kim and steffon both factor the equation x2-4=0 kim thinks that the root is 2 has multiplicity 2, but stefan thinks the root has
faust18 [17]

Given equation is : x^{2}-4=0

Solving it we get,

x^{2}=4

\sqrt{x}=\sqrt{4} and \sqrt{x}=-\sqrt{4}

This gives x=2 and x=-2 or we can say the roots are (x+2)(x-2)

Here Stefan is right, the root has a multiplicity of 1.

Find the axis of symmetry for this parabola
mariarad [96]

The axis of symmetry is 1.

To find this, do -b/2a, putting -8 in the place of b and -4 in the place of a. Proceed to solve to get 1.

The equation provided is vertex form, so to find the needed components, you need to solve for the vertex. To do so, implement 1 in as x and solve for the vertex.

The vertex is 1, -16.

(y - 16) = -4(x - 1)^2

Although it is not exactly vertex form, the only difference is that instead of it being +k at the end, it is subtracted with the y.

Hope this helps!
