Step 1: Given Information

Graph of two functions are given

Part(a) : Step (1) : composition of functions

$(g o f) (- 8) g (f (- 8)) f r o m t h e g r a p h f (- 8) f (- 8) = 2 g (f (- 8)) = f (2) = - 4 g (f (- 8)) = - 4$

Part (b): Step 1: composition of function

$(f o g) (- 8) f (g (- 8)) f r o m t h e g r a p h g (- 8) = - 2 f (g (- 8)) = f (- 2) = 1 (f o g) (- 8) = 1$

Part(c) : Step 1 : composition of functions

$(g o g) (7) g (g (7)) = g (0) = - 6 (g o g) (7) = - 6$

Part(d): Step 1: composition of functions

$(g o f) (- 5) g (f (- 5)) t h e v a l u e o f f (- 5) i s 4 g (f (- 5)) = g (4) = - 6 (g o f) (- 5) = - 6$
