Question

1) whats the difference between f(x)=ln (x+2) and f(x)=2+ln

----------------

2) What's the domain of g(x)=log (x+1)/(x) base 5 .

thx plz answers with explain .

Answer 1

f(x) = ln (x + 2) is a complete equation and f(x) = 2 + ln is not.

domain of g(x) = log (x + 1) / (x) base 5 is
-1 < x < 0, x > 0
