Answer:
D = 1/2 , E = -1/2 , F = -5/2
Step-by-step explanation:
vertical parabola : ( 1,-2), ( -3, 10 ), (4, 31 )
General form ; [tex]x^2 + y^2 + Dx + Ey + F = 0[/tex]
( 1 ,-2 ) = x1, y1
( -3, 10 ) = x2, y2
( 4, 31 ) = x3, y3
hence :
[tex]y1 = ax_{1} ^2 + bx_{1} + c[/tex]
[tex]y2 = ax_{2} ^2 + bx_{2} + c[/tex]
[tex]y3 = ax_{3} ^2 + bx_{3} + c[/tex]
attached below is the detailed solution required
D = 1/2 , E = -1/2 , F = -5/2
