The answer is obviously 3 The domain of g is unrestricted so the only caveat is whether f(x) exists for all values of x Some might argue that g(x) exists even if x doesn't exist but others would argue that since g is a mapping from the domain toF (x) = 2x − 1 f (x) = 2 x 1, g(x) = x 3 g (x) = x 3 Set up the composite result function f (g(x)) f (g (x)) Evaluate f (g(x)) f (g (x)) by substituting in the value of g g into f f Transcript Example 16 Let f(x) = x2and g(x) = 2x 1 be two real functions Find (f g) (x), (f – g) (x), (fg) (x), ("f" /𝑔) (x) f(x) = x2 & g(x) = 2x 1 (f
