Respuesta :
The correct answer is B) The set of all first elements of the function. Let's say you had these three points on a graph of a function: (0.9), (2.6), (4,7). The domain of these three points would be (0,2,4). The domain is just the input for which the function is defined. Hope this helps.
Answer:
The correct option is B) the set of all first elements of the function.
Step-by-step explanation:
Consider the provided information.
Domain: Domain is the set of all values which a function can take or the domain is the set of all first elements of ordered pairs.
For example:
The domain of the polynomial function is the set of all real numbers.
Consider the another example:
A = {(green,mark), (yellow,Kyle), (blue,Elaine)}
The domain is {green,yellow,blue}
Therefore, the correct option is B) the set of all first elements of the function.
