a. what would be the limit at x=2?

# data[].attributes.body
b. only from which side can x get closer to -2?

# data[].attributes.body
c. only from which side can x get closer to 4?

# data[].attributes.body
what happens when x is getting closer to 0? what will the limit be at x=0?

# data[].attributes.body
X-2

# data[].attributes.body
when will the limit exist?

# data[].attributes.body
a, -2

b, right

c, left

d, does not exist

e, left limit equals to right limit

# data[].attributes.body
1. a.-2,

2. b.positive,

3. c.negative,

4. d.doesn't exist,

5. e."positive"="negative"

# data[].attributes.body
a.limf(x)=-2

b.right

c.left

d.it's getting close to zero or one ;it has no limit

e.when x goes close to a value, y will have only one value

# data[].attributes.headline
a.-2 b.left c.right d.y is getting closer to 1 ; when x is at 0, y doesn’t exist e.the limit of a function at any point ; the  limit at infinity 

# data[].attributes.subject
a.-2 b.left c.right d.y is getting closer to 1 ; when x is at 0, y doesn’t exist e.the limit of a function at any point ; the  limit at infinity 

# data[].attributes.body
A:-2

B:right

C;left

D :limit does not exist the value approach to different value from left and right side

E: x¡=0 and x belongs to (-2,4]
