Let f(x) and g(r) be defined as follows:f: (4,0)? R. f(x) = ln(x-4)9: R R. g(x)=x²-5Calculate the following compositions and determine the range and domain of each of them.Please note that drawing a graph of the composed function is not sufficient working to showyour answer for the domain and range.(a) (fog)(x)(b) (gof)(x)
