Determine Whether the Graph Is That of a Function $\{y \mid y \leq-2$

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: all real numbers
range: $\{y \mid y \leq-2$ or $y \geq 2\}$
intercepts: $(-2,0) ,(2,0)$
symmetry: $\mathrm{y}$ -axis

B)
function
domain: $\{x \mid-2 \leq x \leq 2\}$
range: all real numbers
intercepts: $(-2,0) ,(2,0)$
symmetry: $x$ -axis, $y$ -axis

C)
function
domain: $\{x \mid x \leq-2$ or $x \geq 2\}$
range: all real numbers
intercepts: $(-2,0) ,(2,0)$
symmetry: $\mathrm{x}$ -axis, $\mathrm{y}$ -axis, origin

D)
$\text { not a function }$
