Functions Relations and Graphs

Describe the end behavior of the graph.

• x → ∞, y→ ∞ and
  x→ ∞, y→⁻∞

• x → ∞, y→ ∞ and
  x→⁻∞, y→∞

• None of these

• x →∞,y→⁻∞ and
  x→∞, y→⁻∞

What is the range of the following graph?

• R: {-5, -1, 0 , 1, 5}

• R: {-4, -2, 0, 3, 6}

Does the graph represent a function?

• Yes, because the vertical line test shows there are no repeating input values

• No, because the vertical line test shows there are repeating input values

Does this mapping diagram represent a function?

• No, because there are repeating input values

• Yes, because there are no repeating input values

Is relation shown a function?

• YES

• NO

Is the relation a function?

• YES

• NO

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.

What is the domain of the graph?

• [1,∞)

• (1,∞)

• All real numbers

• none of these

• F
• G
• H
• J

A set of ordered pairs is called what?

• Coordinates

• Relation

• Function
