Find vertex of: <br><br> y=(x-4)(x+8)
ki77a [65]

Answer:

(-2,-36)

Step-by-step explanation:

y=(x-4)(x+8)

<u>1) Find the zeros of the parabola</u>

The zero-product property states that any value, when multiplied by 0 will equal 0. Therefore, to make y=0, either (x-4)=0 OR (x+8)=0.

Therefore, x=4 and x=-8.

<u>2) Find the x-coordinate of the vertex</u>

To do this, we take the average of our zeros.

\frac{4+(-8)}{2} \\=\frac{-4}{2} \\=-2

Therefore, the x-coordinate of the vertex is -2.

<u>3) Find the y-coordinate of the vertex</u>

Plug the x-coordinate back into the original equation

y=(-2-4)(-2+8)\\y=(-6)(6)\\y=-36

Therefore, the y-coordinate of the vertex is -36.

Therefore, the vertex of the parabola is (-2,-36).

I hope this helps!

Let's simplify step-by-step.

5x^3 + 3 + 2x^3 − x^2 + 1

= 5x^3 + 3 + 2x^3 + −x^2 + 1

Combine Like Terms:

= 5x^3 + 3 + 2x^3 + −x^2 + 1

= ( 5x^3 + 2x^3 ) + ( −x^2 ) + ( 3 + 1 )

= 7x^3 + −x^2 + 4

Answer:

= 7x^3 − x^2 + 4
