SOLVED EXAMPLE PROBLEM

Find the following limit:

x 2
( x² - x - 2

x² - 5x + 6 ) =

x 2
( (x- 2) ( x + 1)

(x - 2) (x - 3) ) =

x 2
( x + 1

x - 3 ) = ( 2 + 1

2 - 3 ) = (- 3)

[1] (value 10%)

Find the following limit:

x 2
( x³ - 2x² + x - 3 ) = (enter a number or write "undefined")

[2] (value 10%)

Find the following limit:

x 1
( x² - 4

x - 2 ) = (enter a number or write "undefined")

[3] (value 10%)

Find the following limit:

x 2
( x² - 4

x - 2 ) = (enter a number or write "undefined")

[4] (value 10%)

Find the following limit:

x 2
( x - 4

x - 2 ) = (enter a number or write "undefined")

[5] (value 10%)

Find the following limit:

x 3
( 2x² - 3x - 9

x - 3 ) = (enter a number or write "undefined")

[6] (value 10%)

Find the following limit:

x 4
( 2x² - 5x - 12

5x² - 18x - 8 ) = (enter a number or write "undefined")

[7] (value 10%)

Find the following limit:

x 3
( 3x⁴ - 13x³ + 12x²

x³ - 3x² ) = (enter a number or write "undefined")

[8] (value 10%)

Find the following limit:

x 9
(

x - 9

x - 3
)
= (enter a number or write "undefined")

[9] (value 10%)
(One-sided limits) If a relationship between x
and y is defined by the red graph at the right :

Then

x 2⁺
( y ) = (enter a number or write "undefined")

And

x 2^-
( y ) = (enter a number or write "undefined")
