    la parábola es el lugar

    geométrico en el cual los puntos tienen una distancia idéntica, equidistantes,

    de un punto denominado foco, f, y una recta denominada directriz

     

    el radio vector de una

    parábola es el segmento que existe entre un punto cualquiera y el foco.

     

    por la ecuación se observa

    que la parábola abre hacia la derecha, por lo cual podemos usar las siguientes fórmulas

     

    la ecuación ordinaria de la

    parábola es y^2 = 4px, donde p es la longitud desde el vértice de la parábola al

    foco.

     

    la fórmula de la directriz

    es x + p = 0

     

    resolviendo:

     

    y^2-9x = 0

    y^2 = 9x

     

    4p = 9, entonces p = 9/4

     

    entonces el foco tendrá la

    coordenada f(9/4,0)

     

    la directriz vendrá

    expresada por

     

    x + p = 0

    x = -p

    x = -9/4

     

    el problema indica que la

    ordenada es igual a 6, entonces

     

    (6)^2=9x

    x = 36/9

    x = 4

     

    entonces el punto al cual

    hay que obtener la distancia será p(4,6)

     

    calculando se tendrá: pf = 

    pf = 6,25 u
