From the table,
we can see that
[tex]f(1)=2.85786[/tex]
From the graph also we can see that
[tex]f(-100)=6.97831[/tex]
As the negative values of x become larger from -1 through to -1000 we can see that the values increase as it approaches 7
Therefore,
we can conclude that
[tex]\lim _{x\to-\infty}f(x)=7[/tex]
Hence,
The second option 7 is the correct answer
