Answer:


(FG)(2) =20\\

Explanation:

Given


F = \{(0, 1), (2, 4), (4, 6), (6, 8)\}


G = \{(2, 5), (4, 7), (5, 8), (6, 9), (7, 5)\}

Required

(F G) (2)

In functions:


(F G)(x) = (F * G)(x)

Which then gives:


(F G)(x) = F(x) * G(x)

Substitute 2 for x


(F G)(2) = F(2) * G(2)

From the given functions:


F(2) = 4 i.e.
(2,4)


G(2) = 5 i.e.
(2,5)

So:


(FG)(2) = 4 * 5


(FG)(2) =20\\
