Determine Whether the Graph Is That of a Function $\{y \mid y \leq-2$

question 136

Multiple Choice

Determine whether the graph is that of a function. If it is, use the graph to find its domain and range, the intercepts, if
any, and any symmetry with respect to the x-axis, the y-axis, or the origin.
-

• A) function domain: all real numbers range: \( \{y \mid y \leq-2 \) or \( y \geq 2\} \) intercepts: \( (-2,0),(2,0) \) symmetry: \( \mathrm{y} \)-axis
• B) function domain: \( \{x \mid-2 \leq x \leq 2\} \) range: all real numbers intercepts: \( (-2,0),(2,0) \) symmetry: \( x \)-axis, \( y \)-axis
• C) function domain: \( \{x \mid x \leq-2 \) or \( x \geq 2\} \) range: all real numbers intercepts: \( (-2,0),(2,0) \) symmetry: \( \mathrm{x} \)-axis, \( \mathrm{y} \)-axis, origin
• D) \(\text { not a function }\)
