Solution 1

To find the turning point (also known as the vertex) of the parabola given by the equation y=57(x47)2+20 y = 57(x - 47)^2 + 20 , follow these steps:

  1. Identify the standard form of a parabola: The standard form of a parabola that opens upwards or downwards is y=a(xh)2+k y = a(x - h)^2 + k , where (h,k)(h, k) is the vertex of the parabola.

  2. Compare the given equation to the standard form: The given equation is y=57(x47)2+20 y = 57(x - 47)^2 + 20 .

  3. Extract the vertex coordinates: By comparing y=57(x47)2+20 y = 57(x - 47)^2 + 20 to y=a(xh)2+k y = a(x - h)^2 + k , we can see that:

    • h=47 h = 47
    • k=20 k = 20
  4. Write down the turning point: The turning point (vertex) of the parabola is (h,k)=(47,20)(h, k) = (47, 20).

So, the turning point of the parabola with the equation y=57(x47)2+20 y = 57(x - 47)^2 + 20 is (47,20)(47, 20).

Solution 2

Para encontrar el punto de inflexión de la parábola con la ecuación y=57(x47)2+20 y = 57(x - 47)^2 + 20 , sigue estos pasos:

  1. Identifica la forma de la ecuación: La ecuación dada está en la forma estándar de una parábola, y=a(xh)2+k y = a(x - h)^2 + k , donde (h,k)(h, k) es el vértice de la parábola.

  2. Determina los valores de h h y k k : Comparando la ecuación dada y=57(x47)2+20 y = 57(x - 47)^2 + 20 con la forma estándar y=a(xh)2+k y = a(x - h)^2 + k , podemos ver que:

    • h=47 h = 47
    • k=20 k = 20
  3. Escribe el punto de inflexión: El vértice de la parábola, que es el punto de inflexión, se encuentra en (h,k)(h, k). Por lo tanto, el punto de inflexión es (47,20)(47, 20).

Entonces, el punto de inflexión de la parábola es (47,20)(47, 20).
