What are the domain and range of the mathematical function f(x)=x-3
1 answer:
Domain: All Real Numbers
Range: All Real Numbers
Further explanation:
Let us define domain and range first
Domain is the set of all possible inputs for a function on which the function is defined.
While range is the output of the function obtained by inputting domain
Here,
Given function is:
The function will not be undefined on any input, so the domain of the function is all real numbers.
Similarly, the range will also be all real numbers as there is no input which makes it undefined.
