I'm sorry I don't understand the formula you're using there.

The exact task is to approximate the local max and local min (I didn't mean the - or + infinite parts) and to approximate the coords of intersection points.

Like at this point in time I'm not "supposed" to know how to find the exact coords, as it's part a math class. 

Only tools I have is finding roots the basic way if a>1 or Gauss (wich doesn't work because the constant here is 1).

So as of now I have this:

(0,1)

approx: (-2.25,0)

Local (or relative) minimum: approx (0.4, 0.55)

Local (or relative) maximum: approx (-1.5 , 1.375)

Thanks a lot!

Although, I have the find some exact coords:

I found x=0 which is (0,1)

But I have to find y=0

That is why I'm trying to find it's root.

I also have to find the minima and maxima.

I am so sorry.

I just noticed I forgot a "+1" at the end of the polynomial.

That would be :

x^3 + 3x^2 + 2x + 1

Honestly I didn't fully get what you meant there. But my question is this:

If you say x=0 as in "x" is a potential rationnal root of the polynomial, wouldn't it mean that you have divided said polynomial by 0 in the first place?

But obviously we can't divide by 0...

So yah, the x=0, I just don't get it.

My bad I just noticed I didn't need Gauss on this one.

But the constant = 0.

How can you solve this if you can't even find the potential rationnal roots, as 0 cannot be divided?

Duh hahaha my bad. Thanks a lot

I don't speak english so fluently, so I used peak regardless of the direction the opening faces, sorry.

Could you explain to me why 7 (7/10) would = 49/10?

I think I found something:

If Log (A) = x then A = 10^x right?

Then can we say 

log ( (1000  ( square root ( ( 10^x)^3 ) ) ) / ( ( 10^x) ^-1) )      is = to the original equation???

Only rule was to find an algebric expression containing only "x" as a variable that would be equal to the original one.

SOOOORRRRY!

My calculations were so wrong!

14,77257 = n replaced in the first equation does give 18k. 

I am so sorry to have wasted your time guys.

I feel so dumb.

What I just don't understand is how to explain that on paper other than "try and error". Maybe I'm just not aware of some fundamental stuff that is implied in your solution...
