So our equation can be y = $2.50 + $3.25x where y is total cost and x is games played.
The equation is be a function as you cannot play 3 games and get more than one price, etc.
I am pretty sure x (the domain) is "all real numbers" but am unsure what the range is [I am just now learning this too] as I think, depending on the amount of games played, it could go on for a long time (sorry about this fdafdasfda)
(with the extra info you gave \/)
Yeaaa so the domain is all integers over and equal to 1.
(still not 100% sure on the range and I don't want to tell you the wrong thing)
The equation is discrete as we can count the amount of games played and the price.
I know I am missing a piece, but hopefully this helps a bit. Good luck and have a nice day :D
