Question

identify the tables below on whether the relationship is
linear,quadratic,exponential,or inverse variation

x y
1 2
2 4
3 8
4 16

Answer 1

We know this is an exponential equation because of the increase in the y values.

2 * 2 = 4
4 * 2 = 8
8 * 2 = 16
and so on.
Need anything else?

Answer 2

thank you @141823 =) if you dont mind could you help me identify the others? this just happens to be something i dont understand at all.

Answer 3

Yes, I can explain everything except inverse variation. I haven't seen that yet. What grade math are you taking right now btw?

Answer 4

okay thank you.
Im in 9th grade algebra

Answer 5

Alright. Got the questions? And maybe after you can teach me a little about those inverse variations lol

Answer 6

x y
1 -2
2 4
3 10
4 16

x y
1 12
2 6
3 4
4 3

x y
1 16
2 13
3 8
4 1

Answer 7

Ok, for the first one we can see the y values increase by 6

-2 + 6 = 4
4 + 6 = 10
10 + 6 = 16

When the first values increase at a constant rate this is linear. Not to be confused with quadratics, that have the second difference increase at a constant rate. Sounds a little familiar?

Answer 8

okay that makes sense now. i had first put it down as quadratic
