The function f(x) is graphed below. Each small box has width and height 1.

What is the value of \(f(f(1))+f(f(2))+f(f(3))+\cdots+f(f(8))+f(f(9))\) ?

I'll get ya started:

f(1) = ? Look at the x= 1 line to find the value f(1) = 7 (the red dot)

then f(7) look at the value of the function at x= 7 f(7) = 9 (the red dot)

so (f ( f(1)) = 9

Do this with the other 8 parts of the question and sum them together....kinda tedious I know !
