Answer:
<u>The function is:</u>
<u>According to data in the table we have:</u>
- f(1) = 3 ⇒ a(1)ⁿ = 3 ⇒ a*1 = 3 ⇒ a = 3
- f(2) = 12 ⇒ 3*2ⁿ = 12 ⇒ 2ⁿ = 4 ⇒ n = 2
<u>Since we found the values of a and n, the function becomes:</u>
<u>The number of infected to the tenth day:</u>
Sixty-seven times a number, plus eight and nine tenths, is not greater than negative three hundred two
It the answer
