Question 1086077
<font color="black" face="times" size="3">{{{2xy = 1}}}


{{{(2xy)/(2x) = 1/(2x)}}}


{{{y = 1/(2x)}}}


The equation {{{y = 1/(2x)}}} is a function because we can plug in any x value, but x = 0, and we'll get EXACTLY ONE y value as the output. Visually the graph passes the vertical line test to further prove this is a function.</font>
