    Answer :

    y = 2( x-3)^2 +5

    Step-by-step explanation:

    The vertex form of a parabolic functions is

    y = a( x-h)^2 +k

    where (h,k) is the vertex

    y = a( x-3)^2 +5

    Substituting the point into the equation

    13 = a( 1-3)^2 +5

    13 = a*( -2)^2 +5

    13 = 4a +5

    Subtract 5

    8 = 4a

    Divide by 4

    8/4 =a

    2=a

    y = 2( x-3)^2 +5
