Assume that f(3) = 4. Name a point that must be on the graph of y= (5 + f(2x/3))/11$.
We need to make f(2x/3) = f(3)
So... 2x / 3 = 3 → 2x = 9 → x = 9/2 = 4.5
So....remembering that f(3) = 4 we have
5 + f( 2(4.5) / 3) / 11 = 5 + f(9/3) / 11 = 5 + f(3)/11 = 5 + 4 / 11 = 59 / 11
The point is (4.5 , 59/11)
