Giving medal to whoever can help? To open these doors, you must match the number and type of solutions for the following two functions in standard form. f(x) = x2 + 6x – 16 g(x) = x2 +6x + 1 Match the following descriptions of the solutions to each of the functions above. Hint: they each have their own match. Two real irrationals solutions Two real rationals solutions After matching these functions, explain to Professor McMerlock how you know these functions meet each condition. Remember, he is a professor, so use complete sentences.

    if discriminant D=b^2-4ac>0 and a perfect square,then roots are real ,rational and different. if D>0 and not a perfect square then roots are real and irrational.
