I'm trying to decide what career path to take. I was thinking in biomedical engineering, but it would be helpful to know any other jobs to research and find out about.

----How do contractile vacuoles to maintain osmotic balance with their environment?

It seems like I'm asking you for a lot when really this is just one big question I'm haveing trouble with. . I'm hopeing this is all related in some way but I'm not having any luck. Anything or any links will do. Thanks a lot :)

ok, i tried to ask this before but no one seemed to understand what i was asking since the answers had nothing to do with what i was asking so here i go agian:

Lets say i graph the equasion x^2. The graph is a parabola. I want to find the graph of the INVERSE of x^2. This is done by mirroring the parabola over the y=x line.

Now i will find the inverse by using this IMPERFECT method:

flip the graph over the x-axis and rotate it 90 degrees clock-wise using the point of rotation of (0,0).

This method works in finding the inverse graph of the graph of x^2.

HOWEVER, my teacher said this method doesn't work on every graph of any equasion. So, i need to find an equasion, when graphed, does NOT work in finding the inverse of it by the METHOD i displayed earlier.

keep in mind this is pre-calc so no crazy equasions please.

i really hope this makes more sense than my previous question.
