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

question 119

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.
- 2, 0)

• A) function domain: all real numbers range: \( \{y \mid y \leq 9\} \) intercepts: \( (0,-4),(8,0),(0,2) \) symmetry: none
• B) function domain: \( \{x \mid x \leq 9\} \) range: all real numbers intercepts: \( (-4,0),(0,8) ,(2,0) \), symmetry: \( y \)-axis
• C) function domain: all real numbers range: \( \{y \mid y \leq 9\} \) intercepts: \( (-4,0),(0,8),(2,0) \) symmetry: none
• D) \(\text { not a function }\)
