Chapter 6.2, Problem 54E

Explain how to evaluate a definite integral using area -what area should be shaded -where the area is relative to the x-axis -what shapes could be involved -what could make the value of an integral equal a negative value -what could make the value of an integral equal to zero  -what is the order of the endpoints on the integral and what happens if they are reversed.

Please solve

Don't know how to appraoch this.

17 please
