How do you graph #x = (5/2)y^2# on a graphing calculator?

Answer 1

Plug in y= #sqrt(2x/5# or y= -#sqrt(2x/5# to graph this horizontal parabola, which does not represent a function. The former would sketch the curve lying the above x-axis and the later would sketch the curve lying below the x-axis
