Consider the question y=x^2+5-6. determine weather the function has 2 minimum or maximum value. state

Is that supposed to by y = x^2 + 5x -6?  If so, that is a quadratic which is also known as a parabola, and parabolas have only one max value or one min value, depending upon if it is positive or negative.  A positive parabola has a positive leading coefficient, and a negative parabola has a negative leading coefficient.  A positive parabola has a min where a negative parabola has a max.  Ours has one min value. You need to be a bit more clear when you ask your questions, so if that's not what you were looking for as far as an answer, I'm sorry.
