We have, Maximize
$Z=2 x+y$
Subject to constraints
$3 x+5 y \leq 26$$5 x+3 y \leq 30 $$x \geq 0, y \geq 0$
The graph of inequality are
Maximum value $Z = 12$
The extrema of a function are very well known as Maxima and minima. Maxima is the maximum and minima is the minimum value of a function within the given set of ranges.
There are two types of maxima and minima that exist in a function, such as:
