The Trapezoidal rule applied to f fx) dx gives the value 4, and Simpson's rule gives the value 2. What is f(1)?

Use the graph of f(x) below to answer the next 2 questions. 10 f(x) -10 5 10 -10 L 14) dx- 45(2) dx. 4f (x) dx. 9. Find а) — 84 b) 21 c) 84 d) –21 e) None of the above

Please provide , steps , work , and an explanation on how to get the answer

I need help with this question ,pls write neatly so I can understand

4. If f f(x)dx = 14 and f (x)dx = 10, find f f(x)dx. Draw a sketch to justify your answer.
