The function f(x) = 2x + 4 is restricted to a domain interval of -2 ≤ x ≤ 2. Is the domain over the interval continuous or discrete, and what is the range of the function?

• Domain is discrete; Range: -3 ≤ x ≤ -1

• Domain is discrete; Range: 0 ≤ f(x) ≤ 8

• Domain is continuous; Range: -3 ≤ x ≤ -1

• Domain is continuous; Range: 0 ≤ f(x) ≤ 8

The total cost, C, to attend a swim meet for a swimmer competing in x events can be modeled using a linear function. Each swimmer will pay a $3.00 entry fee for each event and $8.75 for lunch. Each swimmer may sign up for a maximum of 5 events. What are the domain and range of the function for this situation?

• Domain: {11.75, 14.75, 17.75, 20.75, 23.75} Range: {1, 2, 3, 4, 5}

• Domain: All real numbers greater than or equal to 1 and less than or equal to 5 Range: All real numbers greater than or equal to 11.75 and less than or equal to 23.75

• Domain: {1, 2, 3, 4, 5} Range: {11.75, 14.75, 17.75, 20.75, 23.75}

• Domain: All real numbers less than or equal to 5 Range: All real numbers less than or equal to 23.75

• (0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100), discrete

• 0 ≤ x ≤ 100, continuous

• 0 ≤ x ≤ 10, continuous
