so all those quadratics have their parent y = x², which has the graph of a "bowl".
and depending on the coefficient, the bowl is wider or not.
the larger the coefficient, the narrower the bowl, the smaller the coefficient, the wider the bowl.
well, 1/2 is smaller then 2, thus y = (1/2)x² is wider than y = 2x².
Answer:
A
Step-by-step explanation:
2(3) + (3) = 9
3(3) - 2(3) = 3
Find the diameter of a circle with circumference of 15.70
Solution: We are given:
The circumference of a circle 
We are required to find the diameter of the circle based on given circumference.
We know that:

rounded to two decimal places
Therefore, the diameter of the circle with circumference 15.70 is 5
If written out it will look like this 1 + 4 * x
