Answer 2

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`
