Domain: # x >4# , in interval notation: #(4,oo)#
Range: # f(x) in RR# ,in interval notation: #(-oo,oo)#.

Explanation:

#f(x) = ln(x-4)#
Domain: #(x-4)>0 or x >4#, in interval notation: #(4,oo)#

Range: #f(x)# may be any real value , i.e # f(x) in RR# ,

in interval notation: #(-oo,oo)#.

graph{ln(x-4) [-12.66, 12.65, -6.33, 6.33]} [Ans]
