Compose f(g(x)) if f(x) = {(1, 3), (2, 9), (5, 7), (11, 9)} and g(x) = {(2, 8), (3, 1), (4, 5), (9, 1), (11, 0)}

To find f(g(x)), we need to first find g(x) and then plug the results into f(x).

g(2) = 8,
g(3) = 1,
g(4) = 5,
g(9) = 1,
g(11) = 0.

Now, we can plug these values into f(x):

f(8) = 9,
f(1) = 3,
f(5) = 7,
f(1) = 3,
f(0) = 3.

Therefore, f(g(x)) = {(8, 9), (1, 3), (5, 7), (1, 3), (0, 3)}.
