XxWhich equation describes the relationship of thegraphs of f(x) and g(x)?O g(x) = f(x) + 1O g(x)=f(x) - 1O g(x) = f(x + 1)O g(x)=f(x-1)

We can check that the blue graph is identical to the yellow graph except it is translated one unit upward.
Assuming that the blue graph corresponds to g(x), we have g(x) = f(x) + 1, and, assuming the blue graph corresponds to f(x), we have g(x) = f(x) - 1.
