    Is it \[y=|\frac{1}{2x}|\]

    Are you planning to sketch or plot?

    absolute value is moving all -ve values to +ve so the right side of the graph stays the same, but since the left side is -ve when u plug in values less than in x. let's say y = -5 , the absolute value will be 5 (-5, -5 ) will be (-5, 5)

    lets create a table. write down an x y table. put a few easy points. -4, -2, 0, 2 4. Then find the y-values for these. This will help you see a little better what lovekblue was trying to say. Absolute value graphs will look like a "V"

    okay, and I would find the y-values by substituting the x values into y=|1/2 x| ?

    do you see that if you graph that the line comes down from the left, hits zero, and takes back up to the right looking like a V. This is the graph!!

    Yup, when in doubt just start picking easy points. Always a quick method to get an idea especially on a test.

    I should let you know about this site. Wolframalpha.com Type in anything you want and it will solve and graph it.
