Review Session Continuity, Differentiability and Major Theorems
Topic 1Continuity
Definitions
A function f is said to be continuous at x = c provided the following conditions are satisfied:
1. f(c) is defined
2. The limit as x approaches c for f(x) exist
3. The limit form #2 and the the value from #1 are the same
Common areas were functions are not continuous
Holes
Vertical Asymptotes
Jumps in graphs
Topic 2Differentiability
Differentiability
A function is said to be differentiable at all places where the derivative exist.
Functions are generally differentiable as long as the function doesn’t have a cusp or point, a vertical tangent line, or a jump in the graph.
Topic 3Mean Value Theorem
Mean Value Theorem, MVT
If f is continuous on the closed interval [a, b] and differentiable on the open interval (a, b), then there exist a number c in (a, b) such that:
Topic 4Intermediate Value Theorem
Intermediate Value Theorem, IVT
If f is continuous on the closed interval [a, b] and w is any number between f(a) and f(b), then there is at least one number c in [a, b] such that f(c) = k
The IVT is often used to show that there must be an x-intercept on an interval
Topic 5Extreme Value Theorem
Extreme Value Theorem
If f is continuous on a closed interval [a, b] then f has both a minimum and a maximum on the interval
