Algebra TNREADY Review Part 3

At the start of the year, the balance in a married couple’s account is 1,750. They decide to each deposit $35 into the account each month.

Which function represents the amount in the account n months after the beginning of the year?

• f(n) = 1,750 + 35n

• f(n) = 1,750 + 70n

• f(n) = 1,750n + 35

• f(n) = 1,750n + 70

The table shows the cost of a gymnastics membership based on the number of months, n, enrolled.

Which function represents the cost of a gymnastics membership for n months?

• C(n) = 45n + 185

• C(n) = 45n + 230

• C(n) = 185n + 45

• C(n) = 230 + 45n

A restaurant manager keeps a record of the total number of customers served since the start of a shift. The table shows the results. Which equation can be used to represent the total number of customers served x hours after the shift begins?

• y = 75x + 60

• y = 75x + 75

• y = 60x + 75

• y = 60x + 135

Study the function represented in the table.

Is the function linear or exponential? Explain the reasoning.

• The function is exponential because there is a constant rate of change; for every increase in x, the y-value increases by 1.3.

• The function is exponential because there is a proportional rate of change; for every increase in x, the y-value increases by a factor of 1.3.

• The function is linear because there is a constant rate of change; for every increase in x, the y-value increases by 1.3.

• The function is linear because there is a proportional rate of change; for every increase in x, the y-value increases by a factor of 1.3.

Which statement best describes the loans Justin is being offered by the two banks?

• Both loans represent linear functions.

• Both loans represent nonlinear functions.

• The loan from Bank 1 is linear, while the loan from Bank 2 is nonlinear.

• The loan from Bank 2 is linear, while the loan from Bank 1 is nonlinear.

Use the information and table given to answer the question. Antonia is researching the growth of E. coli bacteria cells. She charts the population of cells present at given times in the table.

Which statement best describes the change in population of E. coli bacteria cells?

• The population growth of E. coli bacteria cells is best modeled by an exponential function because the population is increasing at a constant percent of change.

• The population growth of E. coli bacteria cells is best modeled by a linear function because the population is increasing at a constant percent of change.

• The population growth of E. coli bacteria cells is best modeled by an exponential function because the population is increasing at a constant rate of change.

• The population growth of E. coli bacteria cells is best modeled by a linear function because the population is increasing at a constant rate of change.
