Question

A computer manufacturer built a new facility for assembling computers. The company made combined profits of $40 million after 4 years. Choose the correct profit function.

a) f(x)=−30x+80
b) f(x)=−40x+4
c) f(x)=40x−4
d) f(x)=30x−80

Answer 1

d) f(x)=30x−80. The correct profit function is f(x)=30x-80.

Step-by-step explanation:

The correct profit function is f(x)=30x-80. The combined profits of $40 million after 4 years indicates that the profit is increasing over time. The slope of the profit function is positive, indicating that the profit is increasing as the number of years (x) increases.
