## anonymous 4 years ago Help please: f(x)=(6)/(x) Using the horizontal line test, determine whether the function is one-to-one. I did the test and it fails the horizontal line test...so does that mean it is one-to-one or not.

1. anonymous

or wait does it fail the horizontal line test? i am confused now!!

2. anonymous

it doesn't fail, i.e. it passes so it is one to one

3. anonymous

looks like $y=\frac{1}{x}$|dw:1328392097965:dw|

4. anonymous

yes...ahh okay that makes sense! thanks satellite73!

yw by the way the inverse is the same function again. it is its own inverse
