Definitions:

**Relation**is a set of ordered pairs.

**Function**is a relation for wich each element of the

**domain**corresponds to exactly one element of the

**range**.

The graph on the right shows the 6 flower species as the

**independent variables**and their native habitats as the

**dependent variables**. The

**domains**are the flowers: plum blossom, lotus, musk rose, ixora, prim rose, foxglove; the

**ranges**of the function are the countries: China, India, Malaysia, England. Since each of these flowers had 1 original nativity this is a function.

In the graph on the right I added the bombax ceiba flower specie, which was distributed in 3 places. The

**domains**are now including plum blossom, lotus, musk rose, ixora, prim rose, foxglove, and bombax ceiba; the new

**ranges**are China, India, Malaysia, England, and Australia. Since 1 of the domain had match with more than 1 range, the function failed and the graph is a relation.
