The profit function for a firm's
commodity is
f (x) = -2x² + 1200x – 100 000,
|
where x is the quantity of the
commodity produced.
A possible re-arrangement of
f(x) = -2x² + 1200x
100 000 = 0
-
for finding a zero of the firm's
profit function with the Fixed-Point
Method is
(2.x2 + 100 000)/1200.
Applying five decimal place rounding
in all calculations, the fourth
Fixed-Point Method iteration
obtained with this re-arrangement
and the initial approximation
x1 = 105 gives x5 =
