Question

find the domain and range of function
g(x)=1n (3x+6)

D:_____________
R_______________
V.A______________

Answer 1

since the domain of y=lnx is x>0, then the domain of g(x)=ln(3x+6) is 3x+6>0.... solve this inequality for x....

Answer 2

setting 3x+6=0 and solving for x will give you the vertical asymptote.

Answer 3

range is the same as lnx

Answer 4

vertical asymptote: -2
am i rite?

Answer 5

ryte...

Answer 6

what about domain?

Answer 7

i am little bit confusing that domain.
(0,00) or (-2,00) domain

Answer 8

the domain starts (but does not include) at the x coordinate of your VA

Answer 9

i get it. thats answer (-2,00)

Answer 10

thanks!! you are extraordinary!
