Hi there, i was wondering if you could help me find the range of this function:
3ln(y + 4) = 2ln(x + 2) 2ln(x + 9) + 3ln(x^2 1)

Best ResponseYou've already chosen the best response.0ok we see that we have ln (y+4) on the left side. so y+4 > 0 , since ln 0 or ln (negative) is not defined. so y > 4 for the range. for the domain we have x + 2 > 0 , x + 9 > 0 and x^2 1 > 0 you take the intersection of these conditions. so x > 2 , x > 9, x > 1 or x < 1 . so the domain is (2, 1) union (1, oo)

Best ResponseYou've already chosen the best response.0Thank you very much for your reply. i spent the whole day looking at it and i couldnt get my head around it. i was trying to gather the terms on the right hand side to simplify the function. guess i was looking at it the wrong way!
