We can think of 3 -- as the answer to the question "How many groups
1 answer:
Answer:
12
Step-by-step explanation:
I am represent 1/4 as a quarter of a circle, and 3 as 3 full circles.
How many quarters of a circle are there in 3 full circles.
There is 4 quarters of a circle in one full circle. Multiplying that by 3, there are 12 quarters of a circle in 3 full circles. So there are 12 quarters in 3.

f(x) = 2 -4x
Step-by-step explanation:
Step 1 :
Given, f(x) = a(x - h)2 + k
Point on the parabola is (3, 6)
Vertex (h,k) = (1,-2)
Step 2:
Substituting the vertex in the equation we have,
f(x) = a(x-1)2 -2
Substituting the point (3,6) in this we have,
6 = a(3-1)2 - 2 => 6 = 4a -2
=> 4a = 8 => a = 2
Step 3 :
Substituting the value for a and the vertex in the given equation we have
f(x) = 2(x-1)2 -2 = 2(x2 - 2x + 1) -2 = 2x2 - 4x
=> f(x) = 2 -4x which is the standard form
