How will the input of f(x + 11) affect the graph of f(x) = x? Explain. The graph of f(x) = x will shift to the right 11 units because positive 11 is being added to x. The graph of f(x) = x will shift to the right 11 units because positive 11 is being subtracted from x. The graph of f(x) = x will shift to the left 11 units because negative 11 is being added to x. The graph of f(x) = x will shift to the left 11 units because negative 11 is being subtracted from x.
