List the following parabolas from widest to narrowest (would like a fast answer)

Step-by-step explanation:

The greater the magnitude of the leading coefficient, the narrower the parabola.

Widest: f(x) = 0.5x²

Next: f(x) = -x²

Next: f(x) = 2x²

Narrowest: 3x²

(largest to smallest)

1. f(x)= 0.5x^2

2. f(x)= -x^2

3. f(x)= -2x^2

4. f(x)= 3x^2

hope this helps, loves!! :)
