The graph is:

Work Step by Step

High coefficients mean the graph is narrower while smaller the coefficient means wider the graph. The coefficients are -$\frac{1}{4}$,5 and -$\frac{1}{2}$.-1/4 is the smallest coefficient so it is the widest graph while 5 is the highest coefficient so it is the narrowest graph. The order from widest to narrowest is y=-$\frac{1}{4}$$x^{2}$,Y=-$\frac{1}{2}$$x^{2}$,y=5$x^{2}$
