how do you write a linear function like this one?

Question

the population increases every 10 years

Answer 1

Let x be the number of years.
Let n be the amount of increase in people
Let p be the initial population in year "0"

f(x) = p + n(x/10)

For example, if you had 100,000 people, and it increases by 10,000 people every 10 years, your equation would be:
f(x) = 100,000 + 10,000(x/10)

This can be simplified to an increase of 1,000 every year.
f(x) = 100,000 + 1,000x

Answer 2

A function can be written in terms of 2 variables, x and y. As long as there are two altering or stable values, a function can be written (in this case). The population is one value, and the amount it increases by is the other. The population is equal to 10 times the amount it is increasing by. Let y be the new population, and x be the increasing factor. y=#+10x, where the # is the starting population

Answer 3

Increases by how much?

Answer 4

increases by how many people?

Answer 5

i think the problem is too vague. other information?

a possible answer is f(x)=10x, where x is the number of years.
