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

The function (F-G)(6) can be rewritten as F(6) - G(6). This means we needs to find the y values in both functions where the x values are 6. Function F has the point (6,8) and function G has the point (6,9). So,:

F(6)=8 and G(6)=9

8 - 9= -1

Answer 2

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) =

"(F minus G) of (6)" - correct?

(6,8) is in F so F(6) = 8

(6,9) is in G so G(6) = 9

(F - G)(6) = 8 - 9 = -1
