Example 1:
For the function f(x) = x + 4, what is the ordered pair for the point on the graph when x = 3p?

Example 2:
If g(x) = 3(x − 2), find the value of x if g(x) = 6

The question is what is F(1) , what dose it equal?

Simply substitute x by its value:

1) 
f(x) = x + 4 ; x = 3p                    f(x) = x + 4 ; 
f(3p) = 3p + 4                            f(1) = 1 + 4
                                                 f(1) = 5
x = 3p                                        (1,5)
y = 3p + 4

2) g(x) = 3(x-2)                           g(x) = 3(x-2)
    g(x) = 6                                  g(1) = 3(1-2)
                                                  g(1) = 3 - 6
6 = 3x - 6                                   g(1) = -3
6+6 = 3x                                       (1,-3)
12 = 3x
x = 4
g(4) = 3(4-2)
g(4) = 12 - 6
g(4) = 6

x = 4
y = 6
