Convert Parabolic Equations to the Standard Form
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 And three points actually will determine a parabola. But I want to do something a … WebThe Standard form of a Parabola is y=ax²+bx+c Let’s do an easy example first Let y=2 (x-1)²-5 we first apply the binomial formula to expand and get y=2 (x²-2x+1)-5 Next, we distribute the 2 to get y= 2x²-4x+2-5 With 2-5=-3 we finally arrive at … dmv near central city ky
