Question

Use the given graph of f to state the value of each quantity, if it exists. (If an answer does not exist, enter DNE.)

Answer 1

f (2) = DNE

f (4) = 4

Explanation:

Answer 2

a.

`\displaystyle \lim_(x\to2^-)f(x) = 3`

b.

`\displaystyle \lim_(x\to2^+)f(x) = 1`

c.

`\displaystyle \lim_(x\to2) f(x) = \text{DNE}`

d. The filled circle tells you what the value of
`f` is at
`x=2`.

`f(2) = 3`

e.

`\displaystyle \lim_(x\to4)f(x) = 4`

f. There is no filled circle included here, hence to value assigned to
`f(4)`.

`f(4) = \text{DNE}`
