Answer:
Step-by-step explanation:
The vertex equation of a parabola is y - k = m(x - h)^2. This can be rewritten as y = a(x - h)^2 + k. Comparing this formula with the given f(x) = 9(x - 5)2 + 6, we see immediately that h = 5, k = 6 and a = 9. The vertex is at (h, k): (5, 6).
x2 - x - 12 = 0
(x - 4) (x + 3) = 0
x(x + 3) -4(x + 3) = 0
x2 + 3x -4x - 12 = 0
x2 -x -12 = 0
Thats cool but where question
whats the question? and i need you to give me a number line. bud
