1.4.1 Finding a new function given a composite function (Case A : First function is given) Example 1 – 3

Example 1
A function f is defined by f : x 2 x + 5  .
Find the function g if f g : x 3 x 8  .

[Note : First function f is given]



Example 2
A function f is defined by f : x 2 x .
Find the function g if f g : x x 2 + 1   .

[Note : the first function f is given]




Example 3
A function f is defined by f : x 2 x + 1  .
Find the function g if f g : x 5 x 2 x + 5 , x 5  .

[Note : First function is given]
