hey....y
here is the question:
find the range of this following expression, hence get the minimum value
[x+2]/[2x^2 + 4x+ 8]

WORK DONE :

What I tried to do was that I tried to find the maximum value of the
denominator but I failewd to reach the destination
-------PLEASE EXPLAIN

What are you asking?

Are you the former mathxyz?
Your "good English" in some of your posts along with "fake(?) bad English"
in others makes me suspicious...
In other words, you're not imitating Kato very well...

 

[sujoy]

sir
Thanks
yea, what I am asking is what should be the minimum value of the expression& for finding that WHY I follow such a method that will be given
in that context

Are you the former mathxyz?

No I am not, I am your "prankstar"

How do you expect to find a range if nothing else is given?
x=1: 3 / 14
x=2: 4 / 24
x=3: 5 / 38
x=4: 6 / 56
...and on and on...

exactly sir;
however can we determine just the minimum value of the expression
anyway I mean whatever be the case that will be the minimum value?
