Don has been tracking the population of a town. The population was 7,220 last year and has been increasing by 1.45 times each year. How can Don develop a function to model this?

f(x) = (7220 ⋅ 1.45)x where 1.45 is the rate of growth
f(x) = 1.45(7220)x where 7220 is the rate of growth
f(x) = 7220(1.45)x where 1.45 is the rate of growth
f(x) = 7220(x)1.45 where 7220 is the rate of growth

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
