Absolute Maximum/Minimum
A function f
has an absolute maximum at c
if f(c) >= f(x)
. We call f(c)
the maximum value of f
.
The absolute maximum is the largest possible output value for a function.
A function f
has an absolute minimum at c
if f(c) <= f(x)
. f(c)
is the absolute minimum value of f
.
The absolute minimum is the smallest possible output value for a function.
- Where the derivative of a function is zero, there is either a peak or a trough.
