Answer:
D)
Step-by-step explanation:
The first step is to find the vertex.
Start with getting your coefficients:
a = 1, b = -6, c = 6
plug them into the equation
Plug that back into the original equation to get y = -3
The vertex is going to be (3, -3)
The equation for Vertex Form is given by
(a) being the coefficient in front of the
(h) being the first point on the vertex (h,k) ({3},-3)
(k) being the second point on the vertex (h,k) (3,{-3})
something noteworthy is that the independent and squared variable in this case will be the "x", namely the graph of that quadratic is a vertical parabola.
so the parabola has solutions at x = -2 and x = 4, and its vertex will be half-way between those two guys, namely at x = 1.
since this is a vertical parabola, its axis of symmetry, the line that splits its into twin sides, will be a vertical line, and it'll be the x-coordinate of the vertex, since the vertex hasa a coordinate of x = 1, then the axis of symmetry is the vertical line of x = 1.
