SOLUTION: Let f be the function defined by f = {(−3, 8), (−2, 9), (−1, 2), (0, 9), (1, 4), (2, 3), (3, −3)} and let g be the function defined g = {(−3, &#872

Rule:

If the ordered pair (a, b) is contained in a function F,
then F(a) = b

---------------------------

(f∘g)(3) means 

Now since the ordered pair (3, 2) is contained in function g,
we know that g(3) = 2.

So (f∘g)(3) 

Now since the ordered pair (2, 3) is contained in function f,

we know that 

So altogether

 (f∘g)(3)
