Determine Whether the Graph Is That of a Function $\{x \mid-9 \leq x \leq 9\}$

question 248

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: \( \{x \mid-9 \leq x \leq 9\} \) range: \( \{y \mid-9 \leq y \leq 9\} \) intercepts: \( (-9,0),(0,-9),(0,9),(9,0) \) symmetry: \( x \)-axis, \( y \)-axis
• B) function domain: \( \{x \mid-9 \leq x \leq 9\} \) range: \( \{y \mid-9 \leq y \leq 9\} \) intercepts: \( (-9,0),(0,-9),(0,9),(9,0) \) symmetry: \( x \)-axis, \( y \)-axis, origin
• C) function domain: \( \{x \mid-9 \leq x \leq 9\} \) range: \( \{y \mid-9 \leq y \leq 9\} \) intercepts: \( (-9,0),(0,-9),(0,0),(0,9),(9,0) \) symmetry: origin
• D) \(\text { not a function }\)
