write the quadratic function f(x)-x^2+14x-50 in the form f(x)=a(x-h)^2+k by completing the square and graph

  • math college algebra -

    I don't know if that is
    f(x) = - x^2 ...
    or
    f(x) = x^2 ...

    Since you needed an equation, I will assume that the - sign was supposed to be an = sign
    If not, make the necessary changes, by factoring out the -1

    y = x^2 + 14x - 50
    = x^2 + 14x +49 - 49 - 50
    = (x+7)^2 - 1

    I will leave the graphing to you.
