Final answer:
The order from narrowest to widest is y = 0.5x², y = 0.75x², y = 5x², y = 6.5x².
Step-by-step explanation:
The order from narrowest to widest is:
- y = 0.5x²
- y = 0.75x²
- y = 5x²
- y = 6.5x²
To determine the order, we can look at the coefficient of the x² term. The narrower the parabola, the smaller the coefficient. So, the parabola with the smallest coefficient, 0.5, is the narrowest. The parabola with the largest coefficient, 6.5, is the widest.
