MATHEMATICS I (MATEMATİK I) - (İNGİLİZCE) Dersi Polynomial Functions soru detayı:

CEVAP:

Let f (x)= ax²+bx+c, a?0 be a quadratic function. The graph of f (x) is called a parabola. In what
follows we use f (x) = y (i.e. y= ax²+bx+c). Parabolas have shapes similar to a soup bowl.If the leading coefficient is positive, the parabola opens upward. If the leading coefficient is negative, the parabola opens downward.
