Here you go, Cheers.

yasafunctionofx =
  ParametricPlot[
   {
    x,
    3 x^5 + 7 x^2 - 7
    },
   {x, -2, 2},
   PlotRange -> {{-8, 8}, {-8, 8}}
   ];


xasafunctionofy =
  ParametricPlot[
   {
    2 y^8 - 5 y^7 - y,
    y
    },
   {y, -2, 2},
   PlotRange -> {{-8, 8}, {-8, 8}}
   ];


Show[
  yasafunctionofx,
  xasafunctionofy
  ]
