If and , what are the roots of ?
I realized that all it means is that the roots of zero or the f(x)=0 or y=0 value are moved up 14 places so the new roots of zero have to come closer ( since it is a positive parabola coefficient on the a value) to the vortex and closer to zero as the parabola got narrower so only -2 and 3 makes sense. If the coefficient was negative the value would get further from zero as the parabola got fatter.
