-20
-15
-5

Answer 1

Did you just have a question a minute ago about where point H was? It was at (-3, -3).

Answer 2

yes but i need help on this one

Answer 3

To be a function, -5 cannot be used. you can't have two points or it will fail the vertical line test.

Answer 4

The answer is -20. If you notice in the table, the x and y values are never the same, so it's -20.

Answer 5

They're asking what can NOT be used. -5 is the only one that has a good mathematical reason.

Answer 6

is the range a set of ordered pairs or first coordinates or second coordinates

Answer 7

Range is the set of possible y values.

Answer 8

If I give you an ordered pair (7, 2). The 2 is the y value. It is the place on the y axis. I can explain what the y axis and x axis are if you need.

Answer 9

so for the range question which of the 3 answers is it

Answer 10

I would say the second coordinates.

Answer 11

ok thanks

Answer 12

It's good to start from the beginning to understand the basics. It's not hard if you have a good website explaining it. Review x-axis and y-axis, Domain and Range. With a little effort this stuff will become a lot easier. Try to put a bit of time into it.
