What are the domain and range of the representative function?

The total cost of attending the State Fair of Texas for one person can be found using the function C(x) = 0.5x + 16, where x is the number of $0.50 coupons used for rides at the fair after paying $16.00 for general admission.

 

What is the domain of the function for this situation?

• All integers greater than or equal to 0

• All integers greater than or equal to 0

• All real numbers

• All integers greater than or equal to 16

The amount of fuel remaining in a gas grill is a function of the number of hours, h, that the grill has been used. This relationship can be modeled using the linear function shown. 

f(h) = 100 − 2h

Part A
Determine a reasonable domain for the situation. Represent the domain using verbal and
symbolic inequality notation. Justify your answer.


 

Part B
Identify the reasonable domain as continuous or discrete.  

 

 

Part C
Determine a reasonable range for the situation. Represent the range using verbal and
symbolic inequality notation. Justify your answer.

Each month, Arnold receives $1,050 for working part-time at his uncle’s camera store. For each camera that he sells, he earns a $125 bonus. Which equation can be used to find Arnold’s total monthly paycheck, P(x), based on the number of cameras that he sells, x?

• P(x) = 1,050x + 125

• P(x) = 125x + 1,050

• P(x) = x + 1,050

• P(x) = 125x
