f(x)=-2ln(x+1)
Find the domain of f.
So, far this is I have:
f(x)=-2ln(x+1)
f(x)=-2e^(x+1)
Can anyone go over this problem step by step with me?
The domain of
$\displaystyle g(x)=\ln(x)$
is the set $\displaystyle (0,\infty)$
so your function is related to the unshifted natrual log by
$\displaystyle f(x)=-2g(x+1)=-2\ln(x+1)$ This shifts the graph one unit left in the x direction so the domain is
$\displaystyle (-1,\infty)$
OK, solution solved thanks for the help.
I would like to know a bit more about how you solved it.
f(x)=-2ln(x+1)
So, what happens with the negative two exactly?
Because the one of my similar problems I solved ln(x+4) and I got
Domain= (-4,\infty).
So, how is the -2 effect the equation?
