It appears you've uploaded a math exam document containing questions related to areas under curves, likely focusing on calculus concepts. To assist with solving or explaining these problems, I can provide detailed solutions for calculating the area under curves, drawing lines between curves, and interpreting the results.

Do you need help with specific questions or examples from the exam? Feel free to point out any particular problems you'd like me to work through.

Here are some related questions that could expand the topic:

1. How do you find the area under a curve using definite integrals?
2. How do you calculate the area between two curves?
3. What is the significance of finding areas under curves in real-life applications?
4. How do you handle curves that cross each other when calculating area?
5. Can the trapezoidal rule approximate the area under a curve?

Tip: When calculating the area under a curve using integrals, always check the limits of integration to ensure correct boundaries.
