    [SOLVED] quick question

    Hi,

    I need some help solving a quick question...

    If the Point (3,10) is on the graph of y = a^x, then what is this point on the graph of
    y = logax?

    This is what I've done:

    y = logax

    a^y = x (boot the log)

    x = a^y

    so does this mean the point on the graph y = logax will be the inverse of the original?

    i.e.) the new point will be (10,3) ?Any help is much appreciated!!

    Regards,

    Jim.

    Inverse of any log function is an exponential function and vice-versa.
