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: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
