The graph of g(x) = x^2 + 2 is a translation of the graph of f(x) = x^2 up by 2 units.
To see why, consider the graph of f(x) = x^2. If we add 2 to this function, we get:
f(x) + 2 = x^2 + 2
This shifts the entire graph of f(x) up by 2 units. Therefore, the graph of g(x) is a translation of the graph of f(x) up by 2 units.
