What is the domain of the given function? {x | x = –6, –1, 0, 3} {y | y = –7, –2, 1, 9} {x | x = –7, –6, –2, –1, 0, 1, 3, 9} {y | y = –7, –6, –2, –1, 0, 1, 3, 9}

we know that

Domain refers to the values of x for which the function exists

For the given function

the domain is

and

the range is

therefore

the answer is the option

A

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.
