A plane takes off and climbs steadily for 15 minutes until it reaches 30,000 feet. It travels at that altitude for 2 hours until it begins to takes 15 minutes at a constant rate. The graph provided below shows the plane's flight.
Height (feet)
000 OE
Time (hours)
a. Identify whether the graph is discrete or continuous
b. Determine the domain and range.
c. Identify key features of the graph (intervals of increase, decrease, and constants) and interpret them in the context of the situation,

Acable company wants to provide cell phone service for residents on an island. the function for the cost of laying the cable from the island to the mainland is c(x)= 6.500 square root x2+4, where x represents the length of the cable in feet. what are the domain and range of the function? a) domain: all real numbers range: all real numbers greater than or equal to 17,000 b) domain: all real numbers greater than or equal to 0 range: all real numbers greater than or equal to 17,000 c) domain: all real numbers greater than or equal to 0 range: all real numbers greater than or equal to 13,000 d) domain: all real numbers greater than or equal to 13,000 range: all real numbers greater than or equal to 0
