Step-by-step explanation:
Since someone answered wrongly I'll try to give the correct answer without the given xs. It won't matter. We're looking for a set of points which satisfy
y = f(x) = x² + 3
A. f(7)=7² + 3 = 52, not -2, so not A.
B. f(-2)=(-2)² + 3 = 7, not 1, so not B
C. f(-2)=7, that's good so far.
f(-2)=(-1)²+3=1+3=4, good
f(0) = 0²+3 = 3, good
f(1)=1²+3 = 4, good
f(2) = 2²+3 = 7, good
Answer: C
We'll rule out D. f(1)=1²+3=4, not -2, so not D.

Answer:
15%
Step-by-step explanation:
The tank's capacity is 200,000 gallons.
170,000 gallons were used.
200,000 - 170,000 = 30,000
30,000 gallons of fuel are still there.
percent = part/total * 100%
percent = 30,000/200,000 * 100% = 15%
