    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

    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
