Why is $(h,k)$ in the vertex formula of a parabola $=a(x-h)^2 +k

Webequal to each other and solve for y. to derive the equation of the parabola. We do this because the distance from (x, y) to (0, p) equals the distance from (x, y) to (x, − p). √x2 + (y − p)2 = y + p. We then square both sides of the equation, expand the squared terms, and simplify by combining like terms. 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 ... WebParabolas always have a lowest point (or a highest point, if the parabola is upside-down). This point, where the parabola changes direction, is called the "vertex". If the quadratic is written in the form y = a(x − h) 2 + k, then the vertex is the point (h, k). This makes sense, if you think about it. uk gb news live
