Identifying Different Function Types

Look at "Graph of Absolute Value Function" on or around page 110. The graph of an absolute value function has all of the following characteristics, EXCEPT which one?

• Its domain is all real numbers.

• Its range is all real numbers greater than or equal to zero.

• It has a vertical line of symmetry through the vertex.

• It has a horizontal line of symmetry through the vertex.

Look on or around page 8, "Functions." Which of the following are ways to test whether a relation is a function? SELECT ALL THAT APPLY.

• If y-values repeat, then it is NOT a function.

• If x-values repeat, then it is NOT a function.

• If a vertical line intersects a graph more than once, then it is NOT a function.

• If a horizontal line intersects a graph more than once, then it is NOT a function.

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.

• Yes, because each x-value has only one y-value paired with it.

• No, because the x-value 11 has two y-values pair with it.

• No, because each x-value has only one y-value paired with it.
