Tickets for a tour of a city cost $5. A tour will only happen when a total of at least 20 tickets and no more than 45 tickets have been sold. The income from ticket sales, y, when there are x tickets sold for the tour can be modeled using a linear function. For one tour, what is the range of the function for this situation? F 0 ≤ y ≤ 20
G 20 ≤ x ≤ 45
H 0 ≤ x ≤ 20
J 100 ≤ y ≤ 225

Triangle xyz has vertices x(1,3), y(0,0)

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (4 points) part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) part c: what would be the domain of the function if the fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)
