6. x=1/2 is suspicious (it causes division by 0); it is also a point of discontinuity.

8. polynomials have no suspicious points and no points of discontinuities.

10. no suspicious points; no points of discontinuities.

12. t=1 and t=3 are suspicious points; t=3 is a point of discontinuity.

16. for continuity f(2) must equal the limit as x approaches 2, that is we must have f(2)=2.

20. the function cannot be continuous at x=2 because of the pole at this point.

34. a=0 and b=3
