Question

The range of which function includes –4?

Answer 1

`y=√(x) -5`

Answer 2

The function
`f(x)=√(x-5)`

Explanation:

The Range of any function is complete set of all possible resulting values of the dependent variable , after substituting the domain.

so, the function
`f(x)=√(x-5)` has range
`f(x)$\geq$ -5`

This includes - 4 .

Hence, the function is
`f(x)=√(x-5)` .
