I Need to find the domain and the vertical asymptotes Let f be the exponential function defined by f(x)= log1/10 ((x4)) Solution log 0 is undefined hence, x-4=0 is our vertical asymptote so, adding 4 both sides we get x-4+4=0+4 x=4 is our vertical asymptotes for domain: (x4)>0 dividing both sides by -1 hence, x-4<0 x<4 is our domain.
