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

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)
$\text { not a function }$
