Question

How do you find the domain and range of `sqrt(16-x^4)`?

Answer 1

Domain: `[-2, 2]`
Range: `[0, 4]`

Explanation:

We can use `x` less than `-2` and `x` more than `2` so therefore domain is
Domain: `[-2, 2]`

Corresponding outputs give values not exceeding 4 and not less than 0. Therefore, range is

Range: `[0, 4]`

God bless....I hope the explanation is useful.
