Question

What is the domain of the function: {(2, 1); (4, 2); (6, 3); (8, 4)}?








A.
{6, 8}







B.
{2, 4, 6, 8}







C.
{1, 2, 3, 4, 6, 8}







D.
{1, 2, 3, 4}

Answer 1

The domain is the set of allowed/possible inputs. In other words, the set of allowed x values.

So you just need to list all of the x coordinates of each point to list the domain.

Answer 2

\(\bf \{({\color{brown}{ 2}}, 1); ({\color{brown}{ 4}}, 2); ({\color{brown}{ 6}}, 3); ({\color{brown}{ 8}}, 4)\} \qquad {\color{brown}{ domain}}\)

Answer 3

I was gonna say that..lol thank you both
