Order the group of quadratic functions from widest to narrowest graph.

Y=-9x^2 y=1/3x^2 y=1/2x^2

The order of the quadratic functions from widest to narrowest graph is as follows:

1. y = -9x^2
2. y = 1/3x^2
3. y = 1/2x^2

The quadratic function with the coefficient of x^2 being the largest (in this case, -9) has the widest graph, whereas the function with the coefficient of x^2 being the smallest (in this case, 1/2) has the narrowest graph.
