Analyzing a Graph In Exercise, analyze and sketch the graph of the function. Label any relative extrema, points of inflection, a
vivado [14]

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.

y'=\frac{1}{x+3}

y''=-\frac{1}{(x+3)^2}

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.
