Order the quadratic functions from widest to narrowest graph.
y = -9x^2, y = 1/3x^2, y = -1/2x^2
The graph of a quadratic function can be determined by the coefficient in front of the x^2 term. The higher the absolute value of the coefficient, the narrower the graph.
Ordering the quadratic functions from widest to narrowest graph:
1. y = -9x^2
2. y = -1/2x^2
3. y = 1/3x^2
