h(7)   .....we go to  "7"  on the x axis   and go up from there  .....note that we intersect the graph at y = 5

 

So

 

h(7)  = 5

 

So

 

h (h(7))  =   h(5)

 

Now....we do the same thing

 

Go to "5" on the axis ....this time...we go down and intersect  the graph at y = -1

 

So

 

h(h(7)) = h(5)  =  -1

 

 

cool cool  cool
