Class Notes 9/26/07
-Passed back quizzes
-Went over factoring
- Learned about continuity of a function
Factor Rules:
Justifying Graphical Methods for Finding Limits (by factoring):
to solve for above you can use factoring OR synthetic division
Continuity:
Function f is continuous at x=c if and only if:
1) f(c) exists
2) limit f(x) as x approaches c exists
3) f(c) = limit f(x) as x approaches c
Cusp: A point where the function is continuous but the derivative is discontinuous
HOMEWORK:
pg. 56 and 57 All Q’s 21, 24, 27, 30… every third problem to #67
study for quiz on Friday over:
- Trig Functions
- Factoring
- What we have been doing so far (including limits)
