WEBWe will learn how to solve different types of problems on parabola. 1. Find the vertex, focus, directrix, axis and latusrectum of the parabola y \(^{2}\) - 4x - 4y = 0. Solution: The given equation of the parabola is y\(^{2}\) - 4x - 4y = 0. ⇒ y\(^{2}\) - 4y = 4x. ⇒ y\(^{2}\) - 4y + 4 = 4x + 4, (Adding 4 on both sides)
WEBDetermine if the parabola has a vertical or horizontal axis: If vertical: the focus is (0, If horizontal: the focus is. p) and the directrix is y = -p. (p, 0) and the directrix is x = -p. Writing a parabola’s equation in standard form. Here are some examples to practice this on.
