Answer
The graph is that of a function.
$\mathrm{a}$.
Domain: $\{x|0\leq x<4\}$ or $[0,4)$
Range: $\{y|0\leq y<3\}$ or $[0,3)$
$\mathrm{b}$.
Intercepts: $(0,0)$
$\mathrm{c}$.
No symmetry.
Work Step by Step
The graph passes the vertical line test
(any vertical line intersects the graph in at most one point.)
The graph is that of a function.
$a.$
The points on the graph have x-coordinates
from 0 (included) to 4 (excluded).
Domain: $\{x|0\leq x<4\}$ or $[0,4)$.
The y coordinates are from 0 (included) to 3 (excluded).
Range: $\{y|0\leq y<3\}$ or $[0,3)$
$b.$
The points on the graph that belong to the axes:
one point, (0,0).
$c.$
No symmetry.
