P12

This problem tests calculating new functions from old ones.
From the table below calculate the quantities asked for:

$\"x\"$	$\"1\"$	$\"0\"$	$\"-1\"$
$\"f(x)\"$	$\"-1\"$	$\"-1\"$	$\"-3\"$
$\"g(x)\"$	$\"-1\"$	$\"1\"$	$\"1\"$

i. (f + g) (1) = f (1) + g (1) =( -1) + ( -1) = -2

ii. f ( f (1)) = f ( -1) = -3

iii. g ( f (1 )) = g ( -1) = 1
