Determine The Value Of Compound (Composite) Functions

                    Lesson 1

Problem:                   Using  f(x) = x + 3  and  g(x) = x + 2

Find, f(g(4))

Step 1: g(x) = x + 2; g(4) = 4 + 2 = 6

Solution f(x) = x + 3; f(6) = 6 + 3 = 9

 Step 2:                        

                                                             Solution                    The answer is:  9

 Step 3:                                                                      

 Complete   

                                                            Try two practice problems:  

Using  f(x) = x – 2  and  g(x) = x + 4

A. Find g(f(1))

B.  Find (g o f)(x)
