Please help, I do not understand the question.

It is a difficult application

One of the trade-offs Tesla faces is between safety and the maximum range someone can drive an all-electric car before having to recharge it. For example, adding steel to a car makes it safer but also heavier, which results in fewer mileage between recharges. Use the three-point curved line drawing tool to draw a hypothetical production possibilities frontier that Tesla engineers face that shows this trade-off. Assume that this trade-off is consistent with increasing costs of added safety. Properly label this curve. Carefully follow the instructions above, and only draw the required object.
