MATH 1146 Unit 9 Composite & Inverse Functions
MATH 1146 Unit 9 Composite & Inverse Functions Guided Notes Rep Il: Practice problems similar to those in your Guided Notes. Tip! See Ex 1 on p. 69 19. Given the following two functions: f (x) = Vx + 1 and g(x) = 3x (2 pts per letter) a) Find (f . g) (1). (f . g) (1) = b) Find (go f) (1). (g . f ) (1) = c) Find (f . f) (8). ( f . f ) (8 ) = 20. Find functions f and g, not equal to x, so that fog = H. (2 pts per letter) Tip! See Ex 3 on p. 71 a) H(x) = 2(x+ 2)2 + 3 (x+ 2 ) - 1 f (x) = g (x) = b) H (x) = 4Vx+1 f (x ) = g ( x ) = C) H (x ) = =+5 f ( x ) =_ g (x) = 2
