WebApr 9, 2009 · The curve y 2 = x represents a parabola rotated 90° to the right. We actually have 2 functions, y = √ x (the top half of the parabola); and y = −√ x (the bottom half of the parabola) Here is the curve y 2 = x. It passes through (0, 0) and also (4,2) and (4,−2). [Notice that we get 2 values of y for each value of x larger than 0. WebGiven a standard form equation for a parabola centered at (0, 0), sketch the graph.
