Step-by-step explanation:
4h² - 2h + 6
h = -2, subtitute
4 · (-2)² - 2 · (-2) + 6 = 4 · 4 + 4 + 6 = 16 + 4 + 6 = 26
Answer: $10
Step-by-step explanation:
$4/40 golf balls = $1/10 golf balls
$1/10 = x/100, x=100/10, x=$10
Vertex form formula: y = a(x-h)^2 +k, with vertex (h,k)
There are multiple ways to find the vertex. One way is to find the roots and then find the x value exactly in between them, because this parabola is symmetrical.
0 = (x - 3)(x + 2), so x = 3 and -2. The point directly in the middle is x = 1/2 = h
To find the y value of the vertex, plug in 1/2 to the equation.
(1/2)^2 - 2(1/2) + 5 = 4.25 = k
y = (x - 0.5)^2 + 4.25
