Reagan buys movies for 5 dollars each. How much will 9 movies cost him?
-determine whether this represents a functional relationship or not, explain why.
-determine whether the problem would be discrete or continuous, explain why.
The nine movies will cost 45 dollars. This is a function as when the problem is graphed (y=5x) the graph is “one to one” meaning it passes the vertical line test. No “x” value will give you multiple “y” values. The data is continuous as when you refer back to the graph, there are no apparent graphs. No “x” values will yield an impossible solution or lack one.
