The vertex of a parabola is at (-4,-3).
PARABOLA IS SYMMETRIC ABOUT VERTEX..SO X=-4 IS THE LINE OF SYMMETRY
If one x-intercept is at (-11,0),
DISTANCE OF THIS INTERCEPT POINT FROM X=-4 IS -11-(-4)=-7
HENCE THE OTHER INTERCEPTING POINT IS AT -4+7=3
what are the coordinates of the other x-intercept?
COORDINATES OF OTHER INTERCEPT = (3,0)
