# Thread: Relationship between X and Y!

1. ## Relationship between X and Y!

Hi all

What is the relationship between X and Y in the fillowing equation:

Y = -5x0.5 ( Y = -5x (to the power of 0.5 ))

Any help appreciated. Thanks.

For example, you could have:

Square Root Proportion
Cube Root Proportion
Direct Proportion
Inverse Square Proportion
Square Root Proportion
Inverse Square Root Proportion
Inverse Proportion

For example, you could have:

Square Root Proportion
Cube Root Proportion
Direct Proportion
Inverse Square Proportion
Square Root Proportion
Inverse Square Root Proportion
Inverse Proportion
$\displaystyle x^{0.5} = \sqrt {x}$

so which option do you think is the answer?

this site may help explaining what all these are. i didn't read through it, but it does answer your question

3. Boy i wish i understood this!

I think it's going to be one of the Inverse options!!!

At a guess i would say Inverse Square Root Proportion!!!

Am i correct?

Cheers for your help by the way. Shall keep a note of the website for further reference!
