What are the 3 types of discontinuity?
-Jump
-Infinite
-Point/ removable
100
lim f(x)
x--> -1 -
1
100
A limit overall exists if...
The limits from the left and right side are equal.
100
What's the domain? Specify open or closed brackets.
(-infinity, +infinity)

What is f(3), when f(x) = x^2 - 8
1
200
What types of discontinuities are not removable?
Jump discontinuity
Vertical Asymptotes
200
If you approach the limit from the left-side what does the limit notation look like for when f(x) approaches 3?
Lim f(x) = ?
x-> 3-
200
lim f(x)
x--> 3
2
200
What's the domain? (Specify closed or open brackets)
(-3, 1]
200
What does it mean when f(3) is a hole?
undefined or DNE
300
What type of discontinuity has a y-value of positive or negative infinity?
Vertical Asymptote
300
x--> 1-
neg. infinity
300
lim f(x)
x--> 1
DNE
300
What's the range? Specify closed or open brackets.
[-5, 4]
300
State the end behavior using limits.
lim f(x) = -infinity
x--> -inf
lim f(x)= infinity
x--> +inf
400
At which x-values, is the graph discontinuous?
x=-4, 2, 4
400
What does this mean?
Lim f(x) = 4
x-> 5+
The limit of f(x) as x approaches 5 from the right is 4.
400
lim f(x)
x--> 2
infinity
400
What's the range? Specify open or closed brackets.

500
State the type(s) of discontinuity along with the location of each.
-Infinite at x=0

-Jump at x=4
-Point at x=6 (also jump)
500

When the left-sided limit doesn't equal the right-sided limit, it is then said that the limit as a whole....
DNE
