a direct variation means, something like y = (some value) * x like say y = 3x so if x = 1, y = 3 x = 2, y = 6 x= 3, y = 9 and so on ----------------------------------------------- inverse variation means $$y=\frac{some\ number}{x}\qquad \textit{for example}\qquad y=\frac{3}{x} \qquad \begin{array}{llll} x&y \\\hline\\ 1&\frac{3}{1}\to 3\\ 2&\frac{3}{2}\\ 3&\frac{3}{3}\to 1\\ &\textit{and so on} \end{array}$$

can you help me with the first one then???

4. anonymous

well... what do you think on the first one notice, "y" seems to always be bigger than "x" is there any factor for that?

5. anonymous

nope so is it inverse?

6. anonymous

or neither?

7. anonymous

hmmm actually.... "y" fluctuates

8. anonymous

what do you mean

9. anonymous

it varies.. is up first.. then down... .is bigger than "x", and then it goes smaller

10. anonymous

ok so what does that mean

11. anonymous

well... looking at their pattern, I don't see a common factor to get an expression on any of of them...thus I'd say neither on all 3
