A function I could think of is the cost of buying bread. If I only buy a single type of bread, then the function is the number of bread that I buy and the output is the total cost.

Let x be the number of bread I buy

f (x) be the cost of buying a certain number of bread

The price of a single bread is 20 cents

f (x) = 0.2x

Domain: x > 0

Range: y > 0
