EC = 10
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.
Well 3+4=7 so you have two different drawings which removes one marble if you draw and then you have 6. so first, you have 3/7 green and 4/7 to draw black marble. After then, you have either a 3/7 green and 3/7 black chance or a 2/7 green and 4/7 black chance to pull a color. you're more likely to pull a black marble first, then after getting a black marble you have a 50/50 chance of pulling either back or green.
