![EXTREMA AND CRITICAL POINTS
c is a critical point of fif either f'(c) = 0 or f'(c) does not exist.
f(c) is an absolute maximum value of fiff (c) >f(x) for all x in the domain of f.
f(c) is an absolute minimum value of fif f(c) < f(x) for all x in the domain of f.
f(c) is a relative minimum value of fiff(c) 2 f (x) for all x near c.
f(c) is a relative maximum value of fiff(c) < f(x) for all x near c.
EXTREME VALUE THEOREM
FERMAT’S THEOREM
If fis continuous on a closed and bounded interval [a, b], then f
Iff(c) is a relative maximum or minimum value, then f'(c) = 0
attains a maximum and minimum on the interval.
ROLLE'S THEOREM
MEAN VALUE THEOREM
Let f be a function which satisfies the following:
Let f be a function which satisfies the following:
1. fis continuous on the closed interval [a, b].
1. fis continuous on the closed interval [a, b].
2. fis differentiable on the open interval (a, b).
2. fis differentiable on the open interval (a, b).
3. f(a) = f (b).
Then there is some c in the interval (a, b) where
Then there is some c in the interval (a, b) where f'(c) = 0.
f(a) – f(b)
f'(c) =
а —Ь
CALCULUS AND GRAPHS
If f'(x) > 0 on some interval (a,b), then f is increasing on (a, b).
If f'(x) < 0 on some interval (a,b), then f is decreasing on (a, b).
First Derivative Test:
Suppose c is a critical point of some function f.
a. Iff' changes from positive to negative at c, then f(c) is a relative maximum.
b. Iff' changes from negative to positive at c, then f(c) is a relative minimum.
c. If the sign of f' does not change while passing c, then f(c) is neither a maximum nor a minimum (it is a saddle point).
If f"(x) > 0 on some interval (a,b), then fis concave up on (a, b).
If f"(x) <0 on some interval (a, b), then f is concave down on (a, b).
Second Derivative Test:
Suppose c is a critical point of some function f.
a. If f"(c) < 0, then f(c) is a relative maximum.
b. If f"(c) > 0, then f(c) is a relative minimum.
c. If f"(c) = 0, then the test is inconclusive. (Could be a maximum, minimum, or saddle).
