The domain of a function is? a. the set of all points on the function. b. the set of all first elements of the function. c. the set of all second elements of the function.

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.

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0
