Unformatted text preview: A map fig - T is injecttre or one-to-one &quot;If for a x x, es whenever x, 7x2 then who fixis / f ( xz ) .&quot; In other words, a graph is one-to-one if it passes the horizontal time test . juriective I may Is surjective if it's image f (5) = T; if for bry y CT there exists in &amp; ES sick that F ( x ) = 4. Those chements X E S with F-( 2):y are inverse images of y. In other words, a graph is surjective if every I has its y according to fo and * Breckin means the graph is both injecting and it passes the horizontal hime lest.
