ANSWER CHOICES WILL BE BELOW PLEASE BE PAITIENT.

I think B or D but I don't know for sure.

Answer 1

solve for 'y'

Answer 2

y = 12/x

Answer 3

plug in a number for x and see what y equals

Answer 4

such as x=3,4,2,6,-3,-4,-6,-2

Answer 5

Yep, then see where the points lie.

Answer 6

you can eliminate some of the choices because they do not represent the graph of a function, for any value x you put in, you can only get out 1 value for y, to test this we will use the ' vertical line test' which means if you have a vertical line on any value of x you should only hit the graph at most 1 time.
