Graph \(x^2=−6y\). Identify and label the focus, directrix, and endpoints of the latus rectum. Solution. The standard form that applies to the given equation is \(x^2=4py\). Thus, the axis of symmetry is the \(y\)-axis. It follows that: \(−6=4p\),so \(p=−\dfrac{3}{2}\). Since \(p<0\), the parabola opens down.In the first scenario we have x 2 = 4 p y x^2=4py x 2 = 4 p y, meaning the parabola opens upwards. If the p p p is negative the parabola will open downwards. In the second scenario we have y 2 = 4 p x y^2=4px y 2 = 4 p x, meaning the parabola will open to the right. If the p p p is negative the parabola will open to the left side.
