# Is the parabola described by y=2x^2 wider or narrower than the parabola described by y=x^2?

Parabola described by $y = 2 {x}^{2}$ is narrower than the parabola described by $y = {x}^{2.}$
Parabola described by $y = 2 {x}^{2}$ is narrower than the parabola described by $y = {x}^{2.}$
Smaller the coefficient of ${x}^{2}$ wider the curve.
