WebJul 24, 2024 · Answer. Choose integers values for x, substitute them into the equation and solve for y. Record the values of the ordered pairs in the chart. Plot the points, and then connect them with a smooth curve. The … WebWith 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. 𝑎 > 0 ⇒ (ℎ, 𝑘) is the minimum point. 𝑎 < 0 ⇒ (ℎ, 𝑘) is the maximum point. 7 comments.
WebQuadratic function in in vertex form : f (x) = a (x - h) 2 + k where (h, k) is the vertex. When a quadratic function is given in vertex form, we can find the vertex easily by taking the values of 'h' and 'k'. When a quadratic function is given in standard form, you can use formula given below to find the x-coordinate of the vertex. x = -b/2a WebMar 2, 2024 · We can write the vertex form equation as: y = a· (x-h)² + k.
