Answer:
The second graph is correct for this function.
Step-by-step explanation:
The company made combined profits of $40 million after 4 years. The profits increased $30 million per year.
Therefore the rate of change of profit function is 30 and the graph of profit function passing through the point (4,40).
Point slope of a linear function is
Add 40 both sides.
Therefore the profit function is defined as
Put x=0
Therefore y-intercept of function is -80. So, second graph is correct for this function.
Y-intercept of first graph is positive and y-intercept of third and fourth graph are more that -50, therefore option 1, 3 and 4 are incorrect.
