Question

How do you find the domain of `f(x) = -4sqrtx`?

Answer 1

`x>=0, [0,oo)`

Explanation:

The domain consists of the values of `x` for which the function `f(x)` exists.

For `f(x)=-4sqrtx,` recall that we need to avoid negative square roots, IE, we can only plug in numbers greater than or equal to zero.

The domain is therefore

`x>=0, [0,oo)`
