Answer:
analyzed & sketched
Step-by-step explanation:
We are given the function: y = In(x + 3)
So first we need to take the first derivative to find the interval of increase and decrease, then the second derivative to find the interval of concave up and concave down.
[tex]y'=\frac{1}{x+3}[/tex]
[tex]y''=-\frac{1}{(x+3)^2}[/tex]
So it is always increasing function, and always concave down function.
Since it is a logarithmic function, x>3.
So, x = 3 is vertical asymptote.
I attached the sketch as a picture.
