Question

Ian sells fresh, homemade pasta at the farmers' market. For every x grams of flour he uses, he can make f(x) bags of pasta.
What does f(500)=6 tell you?

Answer 1

It means that if Ian uses 500 grams of flour, he can make 6 bags of pasta. Equivalently, the point (500, 6) lies on the graph of f, so 500 g of flour yields 6 bags.
