Suppose that during the 1990s, the population of a certain country was increasing by 1.7% each year. If the population at the end of 1993 was 5.4 million, what was the population at the end of 1994? a.
91,800 people
c.
5,400,000 people
b.
5,612,879 people
d.
5,491,800 people

If the population increases by 1.7% every year then

1994 population = 1993 population * .017 + 1993 population

1994 population = 5,491,800

Answer is "d".

Step-by-step explanation:

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
