[giuly]

im trying to finish my packet which is due pretty soon but i got stuck on one problem and im not sure how to start, it asks to find the domain and range of y=ln(x-2) if someone could help me i would really appreciate it

$\displaystyle \text{ Example,the domain of y=ln(x) is }$------$\displaystyle x >0$

$\displaystyle \text{ The domain of y=ln(x+2) is }$

$\displaystyle (x+2) >0$

$\displaystyle x > -2$

$\displaystyle \text{ Notice it must be bigger than zero, Not equal to zero .}$

I advice you to use google search on Domain and range of logarithms.
