lim
x→4
[x/(x + 1)] − (4/5)
-----------------
x − 4

x= 3.9 f(x)=
x= 3.99 f(x)=
x= 3.999 f(x)=
x= 4.001 f(x)=
x= 4.01 f(x)=
x= 4.1 f(x) =

Answer 1

so you have to fill in the table?

Answer 2

i think you should use a calculator

Answer 3

I've tried, but think I am not entering it correctly as I am getting it wrong constantly

Answer 4

( [ 3.9 / ( 3.9 + 1 ) ] - [ 4 / 5 ] ) / ( 3.9 / 4 )

Answer 8

what do you get for the first entry in the table?

Answer 9

why would it be ( [ 3.9 / ( 3.9 + 1 ) ] - [ 4 / 5 ] ) / ( 3.9 / 4 ) instead of ( [ 3.9 / ( 3.9 + 1 ) ] - [ 4 / 5 ] ) / ( 3.9 - 4 )

Answer 10

um, yeah

( [ 3.9 / ( 3.9 + 1 ) ] - [ 4 / 5 ] ) / ( 3.9 - 4 )

is right. (whoops)
