Using it's concept, it is found that the domain and range of the function are given by:
D: [–4, ∞) and R: [0, ∞)
<h3>What are the domain and the range of a function?</h3>- The domain of a function is the set that contains all the values of the input.
- The range of a function is the set that contains all the values of the output.
In this problem, the function is:
The square root function does not exist for negative values, hence the domain is represented by:
The range of the square root function is , which remains the same as there are no vertical translations.
Hence the correct option is given by:
D: [–4, ∞) and R: [0, ∞)
