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)
