Question

Given F= {(0,1), (2,4), (4,6), (6,8)} and G= {(2,5), (4,7), (5,8), (6,9), (7,5)}(F-G) (6)

Answer 1

(F-G)(x) = -1

Explanation:

The notation (F - G)(x) means to subtract each function when x = 6. According to the sets when x = 6 then F is (6,8) and G is (6,9). To subtract the functions, subtract their output values. (F-G)(x) = 8 - 9 = -1.
