How do you solve this? Do you want me to solve for a certain value of f(x)? For example, for f(6), it would be f(5)+2, and we need to know the value of f(5). So, start with f(1) and saunter through the steps!

On the graph of f(x),  f (0)  =  0....  this implies that  the point (0, 0)  is on the graph

 

So....

 

f ( x - 1)   + 2      shifts this point to the right 1 unit and up 2 units

 

So

 

f ( x - 1)  +  2    for    x  = 1    = 

 

f( 1 - 1) + 2  = 

 

f(0) + 2  =   2

 

 

 

 

cool cool cool
