Question

The graph models the profit a group of students are running a tutor business as a function of time. After how many weeks did it take the group to earn a profit ?where is this information located on the graph? The graph is located above the questions

Answer 1

Notice that the function has negative values between week zero and week 5; thus, just after week 5, the group earned a profit (since the graph reaches positive values just after week 5).

The answer is 5 weeks. That information is located at the x-intercept different than x=0.
