The graph of the function f on the interval 0 ≤ x ≤ 9 consists of three line segments and the point (4, −4), as shown in the figure. It is given that integral from 0 to 4 of g of x dx equals negative 6 and integral from 0 to 9 of g of x dx equals 13. Part A: Find the value of integral from 2 to 6 of f of x dx, or explain why the integral does not exist.

Part B: Find the value of integral from 4 to 9 of g of x dx. Show the work that leads to your answer.

Part C: Find the value of integral from 4 to 9 of 2 times g of x minus f of x end quantity dx. Show the work that leads to your answer.
