Finding Domain and Range of a Function

The graph of a function is shown.  What are the domain and range of this function?

• Domain: (-∞, ∞)
  Range: (-∞, 2]

• Domain: [2, ∞)
  Range: (-∞, ∞)

• Domain: (-∞, ∞)
  Range: (-∞, ∞)

• Domain: (-∞, 2]
  Range: [2, ∞)

Identify the Range

• (- ∞, -2 ]

• [ -2, ∞ )

• (-∞, 0)

• [ 0, ∞)

• F

• G

• H

In finding the domain of the rational function r\left(x\right)=\frac{p\left(x\right)}{q\left(x\right)} where p(x) and q(x) are polynomial functions, all real numbers are allowed for x except . . . (Check all that applies.)

• The ones that would make the function undefined.
