IVT (Intermediate Value Theorem)
if f(x) is continuous on [a,b], there exists a point "c" between a and b such that f(a) ≤ c ≤ f(b)
average rate of change
f(b)-f(a)/b-a
F(x) B continuous at x=c if
1- F(c) exists
2- lim F(x)as x->c exists
3- lim f(x) as x-> c = F(c)
differentiability implies
continuity
Definition of the derivative F'(x)=
Lim as X->0 f(x+h) -f(x) / h
Alternate definition of derivative f'(c)
lim x-> c f(x+h)-f(x) / h
A function is not differentiable at x=c if
1- there is a cusp of sharp point at x=c
2- there is a vertical tangant at x=c
3- there is a discontinuity at x=c
Lim f(x) as x->0
find horizontal asymptote
Average rate of change vs Instantaneous rate of change
AROC= f(b)-f(a)/b-a
IROC= f'(c)
squeeze theorem
If f(x) ≤ g(x) ≤ h(x) for all x ̸= a and limx→a f(x) = limx→a h(x) = L, then limx→a g(x) = L
