ANSWER
Domain:
Range:
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]](https://tex.z-dn.net/?f=%5B0%2C%5Cinfty%5D)
.
or
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]](https://tex.z-dn.net/?f=%28-%20%5Cinfty%2C4%5D%20)
.
