5. Implicit Function An implicit function is one that cannot be easily manipulated to the form y = f(x).

6. This is not a function, but it would still be nice to be able to find the slope.

7. Do the same thing to both sides.

8. This is not a function, but it would still be nice to be able to find the slope. Do the same thing to both sides.

9. This is not a function, but it would still be nice to be able to find the slope. Do the same thing to both sides. Note use of chain rule.
