Examples on F of G of x Example 1: Find f (g (x)) when f (x) = √ x + 3 and g (x) = 5 - x Solution: We can find f of g of x (f (g (x)) by substituting g (x) into f (x). f (g (x)) = f (5 - x) = √ 5 - x + 3 = √ -x + 8 Answer: f (g (x)) = √ -x + 8. Example 2: Find the domain of f (g (x)) with respect to the functions from Example 1. Solution: See more The symbol of a composite functionis '∘'.
