Step-by-step explanationgiven
Step 1
Step 1
Domain.
The domain of a function is the set of values that we are allowed to plug into our function, in the case of square roots we need positive numbers ( greater or equal than zero) inside the symbols
so,
so, the x values must be greater or equal than -4, in set notation it is
Step 2
The range of a function refers to the entire set of all possible output values of the dependent variable.
so, we know that for the root the outputs are equal or greater than zero, hence the function g(x) would be.
therefore, Range
so, the answer is
