Determine Whether the Graph Is That of a Function $\{x \mid x \leq 0\}$

question 251

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: \( \{x \mid x \leq 0\} \) range: \( \{y \mid y \geq-2\} \) intercepts: \( (-2,0),(0,-2),(2,0) \) symmetry: \( y \)-axis
• B) function domain: \( \{x \mid x \geq-2\} \) range: \( \{y \mid y \leq 0\} \) intercepts: \( (-2,0),(0,-2),(2,0) \) symmetry: none
• C) function domain: all real numbers range: all real numbers intercepts: \( (-2,0),(0,-2),(2,0) \) symmetry: none
• D) \(\text { not a function }\)
