I REALLY NEED HELP WITH THIS QUESTION, PLEASE HELP!!
Give an example of a logarithmic function g, which has a vertical asymptote
x = –2, and passes through the origin.

y = ln(x+2)  ln 2
= ln[(x/2) + 1)
It becomes vertical at x > 2 and is not defined for x < 2
The added constant makes it go through the origin
