Composite Function Example 1

Example 1
If f : x x + 5 ,   and g : x x 2 + 2 x + 3  , find
(a) the value of gf(2),
(b) the value of fg(2)
(c) the composite functions fg
(d) the composite functions gf
(e) the composite functions g 2
(f) the composite functions f 2



correction for part (c)
fg( x )=f( x 2 +2x+3 )          =( x 2 +2x+3 )+5          = x 2 +2x+3+5          = x 2 +2x+8
