Write an equation of the parabola in intercept form (3, 4) (4,0) (2,0)
An equation of the parabola is y=?​


Sagot :

The equation of the parabola is gotten as;

 y = -4x² + 24x - 32

We are given the coordinates of a parabola to be;

(3, 4) ; (4,0) ; (2,0)

The general form of equation of a parabola is given by;

y = ax² + bx + c

Let's plug in the x and y coordinates as given to us from the question.

  • For coordinate (3, 4), the equation is;

(3²)a + 3b + c = 4

9a + 3b + c = 4  ----(eq 1)

  • For coordinate (4, 0), the equation is;

(4²)a + 4b + c = 0

16a + 4b + c = 0  ----(eq 2)

  • For coordinate (2, 0), the equation is;

(2²)a + 2b + c = 0

4a + 2b + c = 0  ----(eq 3)

  • Solving the 3 equations using an online simultaneous equation solver tool, we have; a = -4; b = 24; c = -32

  • Plugging these values of a, b and c into the general equation of parabola gives us;

       y = -4x² + 24x - 32
