Question 1197835: State the inverse of each relation. Is the inverse a function?
1. {(18, -3), (-13, -10), (-3, 17), (0, -15)}
A. Inverse={(18, -3), (-15, 0), (-3, 16), (-10, -13)} The inverse is a function.
B. Inverse={(17, -3), (-15, 0), (-3, 18), (-10, -13)} The inverse is not a function.
C. Inverse={(17, -3), (-15, 0), (-3, 18), (-10, -13)}The inverse is a function.
D. Inverse={(18, -3), (-15, 0), (-3, 16), (-10, -13)} The inverse is not a function.
E. Inverse={(-18, 3), (13, 10), (3, -17), (0, 15)} The inverse is a function.
F. Inverse={(-18, 3), (13, 10), (3, -17), (0, 15)} The inverse is not a function.
2. {(5, -11), (-19, -19), (-6, -4), (-3, 8), (-12, 5)}
A. Inverse={(-4, -6), (-19, -19), (-11, 5), (5, -12), (8, -3)} The inverse is not a function.
B. Inverse={(-4, -6), (-19, -19), (-11, 5), (5, -12), (8, -3)} The inverse is a function.
C. Inverse={(5, 6), (19, 19), (11, -5), (-5, 12), (-8, 3)} The inverse is a function.
D. Inverse={(5, 6), (19, 19), (11, -5), (-5, 12), (-8, 3)} The inverse is not a function.
E. Inverse={(-5, -6), (-19, -19), (-11, 5), (5, -12), (-12, -3)} The inverse is a function.
F. Inverse={(-5, -6), (-19, -19), (-11, 5), (5, -12), (-12, -3)} The inverse is not a function.

Too much and too primitive.
I mean too much work to do (to write) and too few to learn. Huge disproportion.
