We notice that the output values correspond to the output values of f(x), but the input to f(x) is 1 less than the corresponding input to g(x). For some given value of x, ...
g(x) = f(x -1)

<h3>h(x)</h3>
The input values correspond to those for f(x), but the output values are all 4 more than for f(x).
