The given function y is positive for all x greater than three. Hence, the function In y is ---Select--- in the domain of x. Obtain the natural logarithm of the function y, using the logarithmic propertiesIn ab = In a + In b and In(2) = In a ? In b, where a and b are positive.In y = In(x + 1)? In(x - 3) In(x - 1) In(x + 3)
