Please help me check my answers for these problems Guess the value of the limit (if it exists) by evaluating the function at the given numbers (correct to six decimal places)

Numbers given: -2.5,-2.9,-2.95,-2.99,-2.999,-2.999 9

-3.5,-3.1,-3.01,-3.001,-3.0001

Lim (x--> -3)

Determine the infinite limit

1)

Lim (x--> )

2)

Lim (x-->1)

pay attention in your classes and concentrate the best thing you can do to raise your test scores is to pay attention when you're supposed to be learning the material: in class!

take good notes.

do your homework.

use mnemonics and other tricks.

do practice tests.

note: the best i know.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
