find the domain of logarithmic fuction
f(x) = ln (x-2) 2nd power
Now, it is not clear whether ln (x-2) has 2nd power or (x-2) has 2nd power
In the first case, f(x) will not be defined for x less than and equal to 2
in the second case, f(x) will not be defined for x=2.
logx is defined if
x is greater than 0
