X 11. Find f (9(x)) and 9(f (x)) for the pair of functions. f (x) = a² + 1 g(x) = x – 10 f (g(x)) =x+101 g(f (x)) =x^2+9_ Your answer should be f (g(x)) = x² – 20a + 101, g(f (æ)) = x² – 9 f (g(x)) = (x – 10)² + 1 f (g(x)) = (x² – 20x + 100) + 1 f (9(x)) = a² – 20a + 101 9(f (æ)) = (a² + 1) – 10 9(f (x)) = a? – 9
