Answer:
y greater-than-or-equal-to 0
Step-by-step explanation:
we know that
The domain of a function is the set of all possible values of x
The range of a function is the complete set of all possible resulting values of y, after we have substituted the domain.
we have
Remember that the radicand of the function must be greater than or equal to zero
so
solve for x
The domain is the interval ----> [-5,∞)
For x=-5
so
The range is the interval ----> [0,∞)
