Order the group of quadratic functions from widest to narrowest graph.
y = -9x^2, y = 1/3x^2, y = -1/2x^2
To determine the width of a quadratic function's graph, we can look at the coefficient in front of the x^2 term. The greater the absolute value of this coefficient, the narrower the graph will be.
Ordering the quadratic functions from widest to narrowest:
1. y = -9x^2 (widest)
2. y = -1/2x^2
3. y = 1/3x^2 (narrowest)
