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

question 8

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: \( \{x \mid x>0\} \) range: all real numbers intercept: \( (1,0) \) symmetry: none
• B) function domain: all real numbers range: \( \{y \mid y>0\} \) intercept: \( (1,0) \) symmetry: none
• C) function domain: \( \{x \mid x>0\} \) range: all real numbers intercept: \( (0,1) \) symmetry: origin
• D) \(\text { not a function }\)
