The table below shows the number of visitors to a museum over a seven day period.

Museum Visitors
Day of Week, x 1 2 3 4 5 6 7
Number of Visitors, N(x) 71 84 91 92 87 76 59

Which function best models this set of data?
A.
N(x) = 22x + 49
B.
N(x) = -3x2 + 74
C.
N(x) = -3x2 + 22x + 52
D.
N(x) = 3x + 68

40 i don’t know lololol

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
