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,

Phyllis and chen are saving money to go to a football game. each friend starts with some money and saves a specific amount each week. phyllis made a graph to show the total she has saved at the end of each week. chen wrote an equation to show the total, y, he has saved at the end of each week, x. y = 15x + 15 compare the amount that each friend has when both friends start saving. select the correct answer from the drop-down menu to complete the statement. phyllis starts with $ and chen starts with $
