How do you determine the domain and range of a function?
1 Answer
See below
Explanation:
I will assume
Then, the domain of
Then the range of
To determine the domain and range of a function, first determine the set of values for which the function is defined and then determine the set of values which result from these.
E.g.
Hence, the domain of
Also,
Hence, the range of
We can deduce these results from the graph of
graph{sqrtx [-4.18, 21.13, -6.51, 6.15]}
