Trying to Min max an input number in the positive and negative directions?
f(x)=x^3 formula in excel
Min max formula??
Ideally with ^1.125 where negative input numbers are increased the larger the number (1^1.125=1, 10^1.125=13.33521432), and the same happens with positive numbers in the other direction.
The question is how does one write this formula into excel? It has things on either side of the = sign. I'm trying to min/max a number as an output.
For example
-5 A1 = -25 B1
+5 A2 = +25 B2
-2 A3 = -4 B3
+2 A4 = +4 B4
-10 A5 = -100 B5
+10 A6 = +100 B6
Etc.
Thanks

So be it!.
OK so is there a question in there?
1. Use code tags for VBA. [code] Your Code [/code] (or use the # button)
2. If your question is resolved, mark it SOLVED using the thread tools
3. Click on the star if you think someone helped you

Explain the logic and show us what you want. Attach a sample workbook.

Depending on the input number along the X axis will output the corresponding output number. The sample workbook I have doesn't come close to this since I can't figure it out.
That's a picture of a curve. I asked for a sample spreadsheet. Close, but no cigar ...
A pure guess. In B1 copied down:
=IF(A1<0,(A1^2)*-1,A1^2)

Any good?

It works, thanks, but there's definitely a more mathematic way of doing it that I'm curious about.
What do you mean by "more mathematical"? What's "less methematical" about what I have suggested? What doesn't it do that you need it to do?
You are very cryptic in your responses! Is this a maths question or an Excel question?
I'm not sure if it is "more mathematical", but an alternative would be =SIGN(A1)*A1^2.
