Reciprocal functions have a general form of:

  • [tex]y= \cfrac{a}{x-h} +k[/tex], where a, h and k are constants

Let's see which of the given functions follow same form:

  • [tex]y= \cfrac{1}{x+4}[/tex]            a = 1, h = - 4, k = 0
  • [tex]y= \cfrac{7}{x}[/tex]                   a = 7, h = 0, k = 0
  • [tex]y= \cfrac{2}{x} +5[/tex]             a = 2, h = 0, k = 5

All the other functions are either linear or quadratic functions.
