Answer:
A. The axis of symmetry is the line x = 6.
D. The parabola opens down.
E. The value of h, when the equation is written in vertex form, is positive.
Step-by-step explanation:
f(x) = –3(x – 6)^2 – 11.
This is in vertex form
y = a( x-h)^2 +k
where ( h,k) is the vertex
(6,-11) is the vertex, so line line of symmetry is x=6
a =-3 so the parabola opens down and it has a maximum
The value of h is 6, which is the x coordinate of the vertex
Answer:
A, D, E
Step-by-step explanation:
f(x) = –3x2 + 36x – 119 written in
vertex form is f(x) = –3(x – 6)2 – 11
Vertex form is y = a(x - h)² + k
vertex is (h,k) which is (6, -11)
- axis of symmetry x = 6
- where a = -3 because a<0, the parabola opens down.
- value of h = 6 as the vertex on the x coordinate
