Analysis of Functions I
Increase, Decrease, and Concavity
Definition. Let f(x) be defined on an interval, and let x1 and x2
denote points in that interval.
(a) f is increasing on the interval if f(x1) < f(x2) whenever x1< x2.
(b) f is decreasing on the in

Differentiability and Piecewise Functions
To determine if differentiable at the point of change, 3: = c I
Theorem:
If f (x) is continuous at x=c and lint f'(x) and lint f (x) exist.
i)C . x>c
Then f is differentiable at x = c: if these limits
Differentiability
Piecewise functions may or may not be differentiable on
their domains.
To be differentiable at a point x = c , the function must be
continuous, and we will then see if it is differentiable.
Lets consider some piecewise functions first.
