Suppose the population of a town is 9,800 and is growing 2% each year. a. write an equation to model the population growth. b. predict the population after 7 years. y = 9,800 • 1.02x ; about 11,257 people y = 2 • 9,800x ; about 137,200 people y = 9,800 • 2x ; about 11,257 people y = 9,800 • 2x ; about 1,254,400 people

 First option is correct.

Population after 7 years becomes 11257.

Step-by-step explanation:

Since we have given that

Number of population of a town = 9800

Rate of growth = 2%

Number of years = 7

We need to find the number of population after 7 years:

So, It becomes,

Hence, First option is correct.

Population after 7 years becomes 11257.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
