The document discusses functions from multiple perspectives. It provides two examples of relations represented by ordered pairs and asks the reader to write equations for the relations, and identify the domain and range. It also provides a graph of a relation and asks the reader to represent it as a table, equation, and determine if it is a function.

2. Given a relation represented by the following ordered pairs, write an
equation expressing the relation.
x 1 2 3 4 5
y 1 4 9 16 25
What is the domain and
range of the relation?

3. Given a relation represented by the following ordered pairs, write an
equation expressing the relation.
x 1 2 3 4 5
y 1 8 27 64 125
What is the domain and
range of the relation?

4. Represent the relation, whose graph is provided, as:
a table of values:
an equation:
Is this a function?
