How do you graph x = (5/2)y^2 on a graphing calculator? Algebra Quadratic Equations and Functions Quadratic Functions and Their Graphs 1 Answer bp Apr 1, 2015 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 Answer link Related questions What are the important features of the graphs of quadratic functions?
