Please make things as easy as possible for us...

Answer 6

Your answers are... not close.

1. You're looking for the graph that goes from:
where x=-4 to x=4, and also from y=-4 to y=4.

2. You're looking for the graph that goes from:
where x=-3 to x=5, and also is a horizontal line at y=-1

3. You're looking for the graph that goes from:
where x=-4 to x=2, and also from y=-2 to y=4.

Answer 8

Answer 9

3. no. Notice it says 3 IS a function. Has to pass the vertical line test.

Answer 10

:(

Answer 11

Do you know what the vertical line test is? @shaleiah

Answer 12

no

Answer 13

It's when you draw a vertical line across any part of the graph, and there cannot be more than one point intersecting the graph at the line.

That means an x-oriented (horizontal) parabola would not pass the vertical line test.

Answer 14

If the graph touches the line more than once, then that means there are two x values for each y, which is NOT a function

Answer 15

Do you understand that?

Answer 16

yes

Answer 17

Alright.
Then, by that rule, which graphs would NOT work?

Answer 18

Afterwards, you can find domain off of the remaining graphs that you haven't scratched out of the options.
Remember that the domain is the x-values and the range is the y-values.

Answer 19

Vert. line test - memorize what it is:

Answer 20

Everything alright? @shaleiah

Answer 21

yes..

Answer 22

Are you confused?

Answer 23

There is a straight-line equation which has

domain x=-4 to x=2
and
range y=-2 to y=4

Answer 24

I understand

Answer 25

Okay.

Answer 26

You're good then?

Answer 27

I believe so.

Answer 28

Alright. I wish you luck then ☺ ♣
