1. 3x=|y| (|y|=abs. value of y)

Simplify the following complex fractions.

2. [(3/x)-(4/y)]/[(4/x)-(3/y)]

PLEASE HELP!

**Steve**, Friday, July 12, 2013 at 12:38pm1. what's the definition of even/odd function?

**Anon**, Friday, July 12, 2013 at 12:40pmIf f(-x) = f(x), the function is even.

If f(-x) = -f(x), the function is odd.

If neither is true, the answer is neither.

**Steve**, Friday, July 12, 2013 at 12:41pmwell, you have

3x = |y|

x = |y|/3

f(-y) = |-y|/3 = |y|/3 so even

**Anon**, Friday, July 12, 2013 at 12:44pmWait.. does it matter if it's f(x) or f(y)?

**Steve**, Friday, July 12, 2013 at 12:47pmsure it does. y is not even a function of x, since there are two values of y for each positive value of x.

x can be defined as a function of y, as I did above. In this case, the relation can be shown to be even.
