Answer

The order of the equations from widest to narrowest is y=$\frac{-2}{3}x^{2}$, y=$-2x^{2}$, y=$-4x^{2}$

Work Step by Step

The greater the coefficient is in front of the x value, the more narrow the graph will be. Contrarily, the smaller the coefficient is in front of the x value, the wider the graph will be. When determining how narrow or wide the graph is, ignore the negative sign in front of the coefficients as it does not determine how narrow/wide the graph is.
