{(-9, 7), (-4, 3), (-1, -6), (2, -8), (5, 12), (10, 11)}

Answer 1

\(\{({\color{brown}{ -9}}, 7), ({\color{brown}{ -4}}, 3), ({\color{brown}{ -1}}, -6), ({\color{brown}{ 2}}, -8), ({\color{brown}{ 5}}, 12), ({\color{brown}{ 10}}, 11)\}\qquad \qquad
\begin{cases}
{\color{brown}{ domain }}\\
range
\end{cases}\)

Answer 2

So -9, -4,-1,2,5, and 10 is what I put as my answer?

Answer 3

that is usually taken to be the domain
the first value in each bracket

Answer 4

the second values in each bracket is taken to be the range
think of these as points on the x y axis
each of there is a point(x,y)

Answer 5

each of these*

domain = {-9, -4,-1,2,5,10}
range={7,3,-6,...}
