Continuous at x = a - Answers limit of f(x) as x->a = f(a)
Differentiable - Answers The derivative exists.
Reasons for a function to not be differentiable - Answers not continuous
cusp/sharp corner
vertical tangent
Intermediate Value Theorem - Answers If f(x) is continuous on [a, b], then it must hit all y-values
between f(a) and f(b).
Mean Value Theorem - Answers If f(x) is continuous on [a, b] and differentiable on (a, b), then there
must be a point c in the open interval where f'(c) = (f(b) - f(a))/(b-a)
Extreme Value Theorem - Answers If f(x) is continuous on [a, b], then it has an absolute max and
absolute min on the interval

Second derivative test - Answers Check for local extrema by checking the concavity at critical points
Closed interval method - Answers Check for absolute extrema on a closed interval by checking the y-
