Please look in your text book for this problem Statement  The functions are f(x) = 3x + 4 and g(x) = 5 + x.

a) (f + g)(x)  (Substitute f(x) = 3x + 4 and g(x) = 5 + x)  (Add: ) b) (f g)(x)  (Substitute f(x) = 3x + 4 and g(x) = 5 + x) Apply commutative property of addition: .  (Subtract: ) c)   (Substitute f(x) = 3x + 4 and g(x) = 5 + x) (Using FOIL method)   d)   , (Substitute f(x) = 3x + 4 and g(x) = 5 + x) Because x = 5 then 5 + x = 0, is excluded from the domain of .
