Vertical Asymptotes occur when factors in the denominator = 0 and do not cancel with factors in the numerator
Find the vertical asymptotes and holes (if any) for the following. Don't forget that vertical asymptotes are equations and holes are points!
Vertical Asymptote:
Hole: None
Vertical Asymptote: None
Hole: (1,1) since (x-1) was cancelled, the hole is at x=1. To find the y-coordinate, plug 1 into the reduced equation:
Vertical Asymptote: since
Hole: None
Vertical Asymptote: since ,
Hole: None
Vertical Asymptote: , since and
Hole: None
Vertical Asymptote: , since , , and , and
Hole: None
Vertical Asymptote: since , ,
Hole: None
Vertical Asymptote: None since , , a number squared will never be negative
Hole: None
Vertical Asymptote: None since , and any number squared will never be a negative number
Hole: None
Vertical Asymptote: since , ,
Hole: None
Vertical asymptotes: and since , , and
Hole: None
Vertical Asymptote:
Hole: (3, ) since , (x-3) was cancelled, so the hole is at x=3. To find the y-coordinate, plug 3 into the reduced equation:
Vertical Asymptote:
Hole: None since the vertical asymptote takes care of the hole.
Vertical Asymptote: None
Hole: (-2,-4) since , (x+2) was cancelled, so the hole is at x = -2. To find the y-coordinate, plug -2 into the reduced equation:
Vertical Asymptotes: None
Holes: (3,3), (0,0) since , x and (x-3) were cancelled, so the holes are at x=0 and x=3. To find the y-coordinate, plug 0 and 3 into the reduced equation: 0, 3
Vertical Asymptote: None
Hole: (1,3) since , (x-1) was cancelled, so the hole is at x=1. To find the y-coordinate, plug 1 into the reduced equation:
Vertical asymptote: since
Hole: (-1, ) Since (x+1) was cancelled, the hole is at x= -1. To find the y-coordinate, plug -1 into the reduced equation:
