Hence, the coordinates of the focus are (a, 0) i.e. (2, 0). (ii) The given parabola is of the form x 2 = -4ay, where 4a = 16 i.e. a = 4. Hence, the coordinates of the focus are (0, -a) i.e. (0, -4). reframework uipath docs

WebA parabola is defined as 𝑦 = 𝑎𝑥² + 𝑏𝑥 + 𝑐 for 𝑎 ≠ 0 By factoring out 𝑎 and completing the square, we get 𝑦 = 𝑎 (𝑥² + (𝑏 ∕ 𝑎)𝑥) + 𝑐 = = 𝑎 (𝑥 + 𝑏 ∕ (2𝑎))² + 𝑐 − 𝑏² ∕ (4𝑎) With ℎ = −𝑏 ∕ (2𝑎) and 𝑘 = 𝑐 − 𝑏² ∕ (4𝑎) we get 𝑦 = 𝑎 (𝑥 − ℎ)² + 𝑘 (𝑥 − ℎ)² ≥ 0 for all 𝑥 So the parabola will have a vertex when (𝑥 − ℎ)² = 0 ⇔ 𝑥 = ℎ ⇒ 𝑦 = 𝑘 WebA fixed point is known as a focus. A fixed straight line is known as the parabola directrix. The standard form to represent this curve is the equation for parabola. Whereas it can be calculated via the parabola equation.
