Calculate area of the white region inside circle.
Area of the two white triangles in top left and bottom right:

Area of the two white quarter circles in the bottom left and top right:

Total area of unshaded white region inside circle:

Area of entire circle including the white and shaded regions

Area of shaded region is area of entire circle - area of unshaded white region

Answer:
Step-by-step explanation:
Note that this function is not defined at x = 0; it does have a vertical asymptote which is the line x = 0, as well as a horiz. asymptote which is the line y = 0. This function is odd because the power of x is -1 (a negative odd number). Half the graph appears in Quadrant I: (1, 1), (2, 1/2), (3, 1/3), etc.
The other half is the reflection of the Quadrant I part in the origin, and this is because the function is odd.
