T-shirts at a flea market cost $4.50 each and shorts cost $6 each. You have enough money to buy exactly 12 t-shirts and 9 pairs of shorts. Write an equation in standard form that models the possible combinations of t-shirts and shorts you can buy. (Hint - if you can buy 12 t-shirts and 9 shorts how much money do you have?) *

so then what are you asking?

step-by-step explanation:

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
