Becky has been tracking the population of a town. the population was 5,340 last year and has been increasing by 1.75 times each year. how can becky develop a function to model this?

As this is an exponential function the formula is:
y=a

If:
a=y when x=0 (In this case 5,340)
b=function rule (In this case 1.75)
=# of years
then:

y=5,340

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
