ANSWER

Domain:

$x \geqslant 0$

Range:

$y \leqslant 4$

Step-by-step explanation

The domain refers to the values of x for which the function is defined.

The least value of x is 0.

Therefore the domain is
$[0,\infty]$ .

or

$x \geqslant 0$

The range refers to values of y for which x is defined.

The highest value on the y-axis that the graph can attained is 4. The function decreases without bound.

There the range is
$(- \infty,4]$ .

or

$y \leqslant 4$
