Answer:
Analyzed and Sketched.
Step-by-step explanation:
We are given
.
We need to find the following to sketch the graph.
1) First derivative of y with respect to x to determine the interval where function increases and decreases.
2) Second derivative of y with respect to x to determine the interval where function is concave up and concave down.

The roots are x = -1/2 and x = 1/2 but negative one cannot be possible due to logarithmic function.
x = 1/2 is absolute maximum.

So, concavity is always down.
Here, x = 0 is vertical asymptote.
I attached the picture of sketched graph.
