Question 964900
That description relies on f(x) and one or both of its roots, but does not rely on g(x).
Also, for C on the y axis, C is BETWEEN quadrant 1 and quadrant 2; or BETWEEN quadrant 3 and quadrant 4.


{{{f(x)=x^2+4x-12}}}
ON the y axis, x=0.
{{{f(0)=0*0+4*0-12}}}
{{{f(0)=-12}}}


Point C must be (0,-12).
