given that f(x) = Ln(x), determine which of the following statements is/are true. justify
a. f(x-2) = f(x) -f(2), x>0
b. if f(u) = 2f(v), then v= u^2
c. if f(x)<0, then 0<x<1
given that f(x) = Ln(x), determine which of the following statements is/are true. justify
a. f(x-2) = f(x) -f(2), x>0
b. if f(u) = 2f(v), then v= u^2
c. if f(x)<0, then 0<x<1
The correct answer is c
f(x-2)=ln(x-2)
if f(u) = 2f(v), then u= v^2 not v= u^2
c is correct for a log function
