Answer:
See the graph and explanation below.
Step-by-step explanation:
For this case we have the following function:
The domain for this function is given by:
since the natural log is not defined for negative numbers
, 
We can calculate some points in order to see the tendency of the graph, we can select a set of points for example 
and we can calculate the values for f(x) like this
x=5.5
x=6
That represent the x intercept
x=7
x=8
x=9
x=10
And that represent the x intercept
And then we can see the plot on the figure attached.
Little tip....notice how ur y coordinates are the same....this means that u have a horizontal line which is represented by y = a number...with that number being the y coordinate of ur points.
So ur equation is : y = -3 <===
** if ur x's would have been the same, it would be a vertical line represented by x = a number...with that number being the x coordinates of ur points...but thats only if ur x coordinates were the same
