The given function is
This is a logarithmic function that is defined for
The reason is that, the logarithmic functions are not defined for negative values of x and 0.
Therefore the argument must always be positive.

Therefore the the restrictions is that,
This is also the same as the domain of the function.
The answer to this equation is x=5.
