Answer:
see below
Step-by-step explanation:
lim x/ (x-4)
as x approaches 4 from the left
let x = 3.9
3.9/ (3.9-4) = -39
Let x = 3.99
3.99/ (3.99 - 4) =-399
As we get closer to 4 from the left we get larger and larger so we will get closer to - negative infinity
The limit as shown in the graph is negative infinity
The vertical asymptote is x=4
The horizontal symptote is y =1
