Answer:

C.) The vertex is at (2, 8) and the axis of symmetry is x = 2.

Step-by-step explanation:

I got a 100 on edge

The vertex is at (2,8) and the axis of symmetry is x = 2

What is vertex and axis of symmetry of a curve?

The vertex of a curve is the point where the curve passes its axis of symmetry. While the axis of symmetry is the line that divides the curve into two equal halves.

Analysis:

if y = a[tex]x^{2}[/tex]+bx +c.  then the axis of symmetry occurs at  [tex]\frac{-b}{2a}[/tex] and the vertex occurs at [tex]\frac{-b}{2a}[/tex] and the value of y at [tex]\frac{-b}{2a}[/tex].

comparing the above with the equation h(x) = -2[tex]x^{2}[/tex]+8x

x coordinate for vertex = [tex]\frac{-8}{2 x -2}[/tex]  = 2

y coordinate at x = 2

-2[tex](2)^{2}[/tex] + 8(2) = 8

vertex is at point (2,8)

axis of symmetry is the x coordinate of the vertex which is at x = 2

In conclusion, the axis of symmetry is at x = 2 and vertex at point (2,80 option c
