From the left 
the function is clearly approaching 5, while from the right 
it is approaching -2.
I wrote it down on paper so ya just look at the paper
That length is the distance between (-4, 5) and (3, 2), computed using the Pythagorean theorem as
.. √((5 -2)^2 +(-4-3)^2) = √(9+49)
.. = √58
.. ≈ 7.616
.. √((5 -2)^2 +(-4-3)^2) = √(9+49)
.. = √58
.. ≈ 7.616
