Mean Value Theorem
if f(x) is continuous on [a,b], and diferentiable on (a,b), and there is a point c where the instantaneous rate of change is equal to the avg. ROC or the slope of the tangent line between a and b
Extreme Value Theorem
f(x) is continuous on the closed interval [a,b] then it has a min and a max
Extrema (max)
the value of c on f(x) with an interval I, f(c) is greater than or equal to all f(x) for all values of x on the interval
extrema (min)
the value of c on f(x) with an interval of I, f(c) is less than or equal to all f(x) for all values of x on the interval
critical number
is f is defined at c, and f’(c) = o or is undefined/not diferentiable, then c is a critical # of f
transition pt
if f’(x) transitions from increasing to decreasing or vice versa
inflection pt
if f’‘(x)= 0 or undefined, ONLY if concavity changes
concave up
f’(x) is increasing, f’‘(x) is positive
concave down
f’(x) is decreasing, f’‘(x) is negative
2nd derivative test local min
if f’‘(x) is positive at a critical number
2nd derivative test local max
if f’‘(x) is negative at a critical number
rolles theorem
f(x) is continuous on closed interval [a,b] and diferentiable on same Open interval, and the value f(a) = f(b) then there must be 1 value c between a,b where f’(c)=0
intermediate value theorem
if f(x) exists on every value on the interval [a,b], then for any value L between f(a) and f(b) there will be a c where f(c)= that L
