What are the domain and range of the function f(x)=log(x-4)-3

The domain and range are:

D=(4,∞),{x|x>4}

R=(-∞,∞),{y|y∈R)

Look at this and see if it

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
