How to know if a parabola opens sideways - Quora

Webb3 feb. 2024 · Obviously, the axis of symmetry is a horizontal line ( a line perpendicular to y-axis). Also, the focus lies to the right of the vertex so the parabola will open up rightward. #(y-k)^2 = 4 a (x-h)# #a = 6 - 2 = 4# as y coordinates are the same. Since the focus lies to the left of vertex, a = 4 #(y-3)^2 = 4 * 4 * (x - 2)# WebbNot all parabolas are congruent to the basic parabola. For example, the arms of the parabola \(y=3x^2\) are steeper than those of the basic parabola. The \(y\)-value of each point on this parabola is three times the \(y\)-value of the point on the basic parabola with the same \(x\)-value, as you can see in the following diagram.
