Y = 3x....where y is # pgs read and x = # of minutes
0 minutes....x = 0
y = 3(0)
y = 0
ordered pair (0,0)
1 minute...x = 1
y = 3(1)
y = 3
ordered pair (1,3)
2 minutes...x = 2
y = 3(2)
y = 6
ordered pair (2,6)
3 minutes...x = 3
y = 3(3)
y = 9
ordered pair (3,9)

Answer:
1367 people
Step-by-step explanation:
The wording "a rate proportional to the number" indicates the function is exponential. The growth factor is 1200/1000 = 1.2 in 7 days, so the exponential function can be written ...
i(t) = 1000(1.2^(t/7))
After 12 days, the number infected is modeled as ...
i(12) = 1000(1.2^(12/7)) ≈ 1367
About 1367 people are infected 12 days after discovery.
