Answer:
The correct option is A.
Step-by-step explanation:
If a line passes through two points and
, then the equation of line is
Let y be the profit (in millions) after x years.
From the given graph it is clear that the line passes through the point (1,-100).
The company paid for these costs and made combined profits of $80 million after 4 years. It means the graph passes through the point (4,80).
The line passes through (1,-100) and (4,80). So, the equation of line is
Subtract 100 from both sides.
The function form is
Therefore, the correct option is A.
