Question

What is the domain of a function?

A) All the values of the outputs of a function resulted by the inputs
B) The input values of a function that would yield outputs
C) The demeaning part of the function
D) The name given to the horizontal and vertical values of the function

Answer 1

The domain of a function represents the set of possible input values that yield valid outputs.

Step-by-step explanation:

The domain of a function represents the set of possible input values for the function that would yield valid outputs. In other words, it is the set of all the input values that the function can take. For example:

1. If X represents the student's major, the domain of X would be all the majors offered at the university, plus undeclared.
2. If Y represents the number of classes taken in the previous semester, the domain of Y would be the integers from zero to the upper limit of classes allowed by the university.
3. If Z represents the amount of money spent on books in the previous semester, the domain of Z would be any amount of money from zero upwards.

The domain of a function is an essential concept in mathematics as it helps define the range of valid inputs for a given function.Final answer:
