A)
$\begin{array}{l}\text { function } \\\text { domain: all real numbers } \\\text { range: }\{\mathrm{y} \mid \mathrm{y} \leq 9\} \\\text { intercepts: }(0,-4) ,(8,0) ,(0,2) \\\text { symmetry: none }\end{array}$

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) not function
