The quadratic relation Ax^2 +Cy^2 +Dx + Ey + F is graphed. the values of the x-intercepts 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

  • math -

    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.
