y=1/x
how would you describe this? I dont understand the answer in my book.

Answer by RAY100(1637)   (Show Source):
You can put this solution on YOUR website! y =1/x,,,,also called the reciprocal function
,
there is a horizontal asymptote at ,, y=o
,
and a vertical asymptote at x=0
,
to rough sketch this, draw a standard x - y coordinate system.
sketch in asymptotes, (same as x,y axis)
,
starting at far left, x=- infinity, y is on the negative side of zero( approaches zero),
going to right this function curves downward, to - infinity as x approaches zero.
,
skipping over the x=0 asymptote, The function picks up at + infinity
as we go right it curves down to approach y=0 as x = + infinity
,
in short in the 3rd quadrant it is a "u" vertex at (0,0) pointed down and to left,
in the 1st quadrant, it is a "u" vertex at (0,0) pointing up and to right. NOTE that the vertex does not touch (0,0) , but only approaches along the 45 degree line, y=x.
,
hpoefully this helps
