WebGraph the equation. y=-2 (x+5)^2+4 y = −2(x + 5)2 + 4 This equation is in vertex form. y=\goldD {a} (x-\blueD h)^2+\greenD k y = a(x − h)2 + k This form reveals the vertex, (\blueD h,\greenD k) (h,k), which in our case is (-5,4) (−5,4). It also reveals whether the parabola opens up or down. Since \goldD a=-2 a = −2, the parabola opens downward. WebIn math, a quadratic equation is a second-order polynomial equation in a single variable. It is written in the form: ax^2 + bx + c = 0 where x is the variable, and a, b, and c are constants, a ≠ 0. How do you know if a quadratic equation has two solutions? A quadratic equation has two solutions if the discriminant b^2 - 4ac is positive.

WebFor standard form: y=Ax^2+Bx+C Look at the coefficient of the x^2 term. If "A" is positive, the parabola opens up. If "A" is negative, then the parabola opens down. For Vertex Form: y=a (x-h)^2+k The sign of "a" determines … WebTranscribed Image Text: Given the function below f(x) = -80x³ + 144 Find the equation of the tangent line to the graph of the function at x = 1. Answer in mx + b form. L(x) Use the tangent line to approximate f(1.1). Web𝑦 = 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 = … emslie march clarks
