We see that the differences are -9, -3, +3, and +9.  Thus, we see that the function is symmetric about x=2 (I'm assuming the five values correspond to x=0, 1, 2, 3, 4) and increases at a rate similar to (x-2) squared.  With that in mind, we classify this function as a parabola, as the standard form of a parabola (y=a(x-h)^2 + k) shows similar growth to this function.

docker41 [41]

Answer:

385 golf balls

Step-by-step explanation:

margin of error = (z*)(s) / sqrt n

where z* = 1.96 with 5%/ 2 = 0.025 area in each tail

margin of error = (z*)(s) / sqrt n

1.2 yards = (1.96)(12 yards) / sqrt n

solve for n

n = 384.16

385 golf balls (always round up)

Let f(x)=(4x^2-11)^3 and g(x)=4x^2-11. given that f(x)=(h^o g)(x), find h(x).
lozanna [386]
So, f(x) is a composite function. This means that g(x) is inside of h(x); in other words, you would substitute g(x) for x in h(x).

Something happened to g(x) (in the form of h(x)) to turn it into f(x). You should notice that f(x) is simply g(x) raised to the third power.

Therefore, h(x) = x^3

You can check this by working it backwards.

Start with: h(x) = x^3
Substitute: x = g(x) = 4x^2-11
Now you have: h(x) = (g(x))^3 = (4x^2-11)^3

Hope this helps!
