• Substitute in the first equation, y = 5 or 4 The numbers are 5 and 4. Mathematical Modelling with Quadratic Functions. There are quite a few real life situations that can be modelled by a quadratic function in an accurate way. For instance, the motion of a ball, thrown upwards to move under gravity, can be easily modelled by a quadratic equation.
For a quadratic equation ax 2 +bx+c = 0 (where a, b and c are coefficients), it's roots is given by following the formula. The term b 2-4ac is known as the discriminant of a quadratic equation. The discriminant tells the nature of the roots.
