Question

Please help me!

Is this an inverse relation.... 2x+4y=6

Explain?

Answer 1

We usually are asked if two functions are inverses, or find the inverse. Is there more to this question?

Answer 2

No...

Answer 3

Have you been working with functions being inversely proportional?

Answer 4

Um I don't think so.... we've been working with inverse variations.

Answer 5

ok, that is what I needed. When a function varies inversely, it can be written as \[y = {k \over x}\]

If we solve this function for y, we get

\[2x+4y=6\]\[4y=-2x+6\]\[y = {-2 \over 4}x+{6 \over 4}\]

which isn't in the same form as y = k/x so this function is not an example if inverse variation.

OK?

Answer 6

Oh thanks so much!
