Q

must points of inflection always be differentiable?

A

no, in fact points of inflection can ONLY exist as a zero or an undefined value (f”(x) = 0 or x/0)

Q

What are the 3 cases for horizontal asymptotes?

A

numerator >denominator degree: none

equal: whatever coefficient is next to the highest power variable

numerator lower degree than denominator: y = 0

Q

first derivative test

A

using the I/D test, if f’(c) goes from negative to positive = min, from positive to negative = max

Q

second derivative test

A

if f’(c) = 0 (min/max as determined by first derivative test) and f”(c) = positive, then minimum, and if negative, then maximum (CU vs CD)
