Answer:
Option D
Step-by-step explanation:
Let the manufacturing unit operates with the maximum capacity = x
Since manufacturing unit currently operates at 80%
So function f(x) that models the current capacity of the unit will be
f(x) = (0.80)x
Given profit function for the unit at optimum output is
p(x) = ( -0.1) x² + 80x - 60
so composite function giving the unit's current profit function will be
p[f(x)] = (-0.1) (0.8x)² + 80(0.80x) - 60
= -(0.1) (0.64x²) + 80 (0.08x) - 60
= - 0.64x² + 6.4x - 60
Option D will be the answer.
