Explanation below.

Explanation:

Simply graph the function g(x) = logx

graph{logx [-10, 10, -5, 5]}

then, shift it upwards 4 units:

graph{logx + 4 [-9.67, 10.33, -2.36, 7.64]}

In general, for any function f, the graph of the function h(x) = f(x) + c, where c is a constant, is the graph of f, shifted upwards c degrees. (If c is negative, it means the shift is downwards instead)
