Answer 1

okay

Answer 2

I'm confused, why did you repost this?

Answer 3

to put the numbers nexts to them sorry

Answer 4

No problem. Do you understand my explanation, though?

Answer 5

yeah

Answer 6

Alright. Also, for reference, if they ask for range, it's the same thing, except range requires that you state the y values instead.

Answer 7

{-11, -4, -1}

Answer 8

first one

Answer 9

{-9, -5, 0, 1, 1, 3, 5, 8}

Answer 10

\[r=\left\{ \left( x1,y1 \right),\left( x2,y2 \right),\left( x3,y3 \right),\left( x4,y2 \right)\right\}\]
\[Domain=\left\{ x1,x2,x3,x4 \right\}\]
\[Range=\left\{ y1,y2,y3 \right\}\]
