Unformatted text preview: g ◦ f . It is the same as the codomain of the function g: A = { , 1 , 2 , 3 , 4 } iii. (6 points) Give the graph of g ◦ f as a set of ordered pairs. { ((0 , 0) , (1 , 1) , (2 , 2) , (3 , 3) , (4 , 4) } 3. (6 points) Find the inverse function of f if it exists. f : R → R , f ( x ) = x/ 2 + 1 This function is onetoone and onto. Onetoone: ( f ( x 1 ) 6 = f ( x 2 )) → (( x 1 / 2 + 1) 6 = ( x 2 / 2 + 1)) → ( x 1 6 = x 2 ) y = x/ 2 + 1 x = 2( y1) f1 ( x ) = 2( x1)...
