Nonlinear Inequalities

[GAspeedProtege]

How do you solve them? I didn't go to school for that part, hehe.

Heres one to work on.

(1+x)/(1-x) >= 1

 

[CatD399]

looks like zero is your only answer here...

 

[jersey_emt]

0 <= x < 1

 

[Moeed]

when some thing is set up like that it equals a negative one.

 

[GAspeedProtege]

the book says to make a table or some crap, its confusing.

 

[GAspeedProtege]

ok wait, it all makes sense now, the table crap was ******* with my head.

 

[CatD399]

0 <= x < 1

ah yes, i see now....

 

[Prodigy]

I did that in algebra 1...

Here's a good equation for you 40 yrs old + Liberal Arts Degree w/math major = (loser)

hehe

 

[Liquidturbo2000]

Heres how you make a table.

Solve for X or any value of X that makes the equation undefined.

In this case, 0 and 1

make a number line

{--- 0 ----- 1 -----}

test values in each region, and see what sign you get.

{--- 0 ----- 1 -----}
- + -

Notice that zero gives a positive ans too
so

0<= x < 1 or in Interval Set Notation, [0,1)

Cheers.
Oh, you have do this for all rational functions if you want to work out the values by hand.

Yeah, the only difference between linear and non-linear is that instead of 1 or 2 answers, you get a range of possible answers. They work basically the same.

MSPinVA...that quote in your sig from snl is classic...jimmy fallon is hilarious...lol
