## lalaland936151 Group Title Please help me! Is this an inverse relation.... 2x+4y=6 Explain? 2 years ago 2 years ago

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

2. lalaland936151 Group Title

No...

3. TransendentialPI Group Title

Have you been working with functions being inversely proportional?

4. lalaland936151 Group Title

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

5. TransendentialPI Group Title

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?

Oh thanks so much!
