Answer:
-7
Step-by-step explanation:
Answer:
<u><em>Y =0</em></u>
Step-by-step explanation:
<u><em>The midline is the y value that runs straight through the middle of the wave. If you can picture the standard sine function graph. f(x) = Sin(x) reaches a maximum y = 1 and minimum y = -1 so the midline is y =0.</em></u>
-3x^2 + 12x -6
a = -3
b = 12
We calculate the vertex "x" value with this formula:
(vertex "x value") = -b / (2*a)
(vertex "x value") = -12 / -6
The vertex "x" value equals the axis of symmetry value.
The axis of symmetry is at x = 2.
