Answer
$1$ ,$2$
(sample answer)
Work Step by Step
The graph contains points (x,f(x)).
The range of the function ( the set of values $f(x)$ ) contains any x from the set of real numbers,
except from the interval $(0,3].$
The answer can be: any two numbers from this interval,
such as $1$ and $2$.
(The graph has no intersections with the lines $y=1$ or $y=2$,
which means that no point on the graph has the y-coordinate 1 or 2.)
