Given: F = {(0, 1), (2, 4), (4, 6), (6, 8)) and G = {(2,5),(4.7), (5,8), (6, 9). (7.5)}

Answer:
(f + g) (2) = f (2) + g (2) = 4 + 5 = 9
(f - g) (6) = f (6) - g (6) = (input the chosen values)
(fg) = f*g = (input the chosen values)
Slope is the change in y over the change of x. So for the first two points are 4-4 over 6 +2, that turns into 0 over 8 and that's just 0=slope
The second one you just do that same thing and then the answer is -7 over 0 which is an undefined slope
x in (-oo:+oo)
2/7 = x/14 // - x/14
2/7-(x/14) = 0
2/7-1/14*x = 0 // - 2/7
-1/14*x = -2/7 // : -1/14
x = -2/7/(-1/14)
x = 4
x = 4
i hope this helps
