The quadratic relation Ax^2 +Cy^2 +Dx + Ey + F is graphed. the values of the xintercepts of the graph are dependant on the values of the paramters
a) A and D only b) C and E only c) C,E and F only d) A,D and F only

AX^2 + CY^2 + DX + EY +F
At the points where the curve crosses
the X axis, Y = 0, So the equation
becomes AX^2 + DX + F. To solve this
equation for X, we need the values of
A ,D , and F. ans. = d.
