I think it is 34 but I am not sure. You should get 2 more answers to confirm the answer.
Answer:
domain: (-∞ , ∞)
range: (-∞, 2]
Step-by-step explanation:
the domain is the set of values of what the x value can be. This function is parabolic and upside down, it can have a range of x values from - infinity to positive infinity. The function is most likely y=-x^2 +2
range is the output (y values) the function can possibly have. the max is 2 and includes 2 so we use bracket for that. The smallest y value can reach towards negative infinity.

<span>1 Liter = 1.05 quart.
1/1.05 Liter = 1.05/1.05 quart = 1 quart.
Replacing this value of quart in the equation below.
1 gallon = 4 quarts
1 gallon = 4 * 1/1.05 Liters
1 gallon = 3.80952380952
Total oil consumption per year in gallons is 600,000,00
So, total oil consumption per year in liters is obtained by:
600,000,000 * 3.80952380952 = 2285714285.71 liters
Converting to scientific notation, we have 2.28571 * 10^9 liters.</span>
