Is  the  relationship  between  the  variables  in  the  table  a  direct  variation,  an  inverse variation,  both,  or  neither?   if  it  is  a  direct  or  inverse  variation,  write  a  function  to model  it. x   2 5    20   40 y   40   20   5   2a.) neitherb.) inverse variation; y = 20/xc.) direct variation; y =20xd.) direct variation; y = x+15

The table shows that as x increases, y decreases. This appears to be an inverse variation. However, the given inverse vaariation in b) does not fit, since if y = 20/x, x = 2 should give y = 10. Also, x = 5 should give y = 4. Therefore, none of these choices is the right answer, so this is A.In an inverse relation, the product of x & y should be a constant, but that is not true in this case.
