Answer:
Option A.
Step-by-step explanation:
The general form of a quadratic function is
It means, power of y should be 1 and highest power of x should be 2.
In option A,
It is a quadratic function.
In option B,
Here, power of y is 2. So, it is not be a quadratic function.
In option C,
Here, highest power of x is 3. So, it is not be a quadratic function.
In option D,
Here, highest power of x is 1. So, it is not be a quadratic function.
Therefore, the correct option is A.

Step-by-step explanation:
Usando las relaciones entre velocidad, distancia y tiempo, se encuentra que ella condujo a una velocidad media de 90,5 km/h.
--------------------------
La <u>velocidad </u><u>es la distancia dividida por el tiempo</u>, por lo que:
![v = \frac{d}{t}](https://tex.z-dn.net/?f=v%20%3D%20%5Cfrac%7Bd%7D%7Bt%7D)
- Total de 135,75 km, o sea,
![d = 135,75](https://tex.z-dn.net/?f=d%20%3D%20135%2C75)
- Llego en 1,5 horas, o sea,
![t = 1,5](https://tex.z-dn.net/?f=t%20%3D%201%2C5)
La velocidad es:
![v = \frac{d}{t} = \frac{135,75}{1,5}](https://tex.z-dn.net/?f=v%20%3D%20%5Cfrac%7Bd%7D%7Bt%7D%20%3D%20%5Cfrac%7B135%2C75%7D%7B1%2C5%7D)
División de decimales, o sea, seguimos multiplicando los números por 10 hasta que ninguno sea decimal:
![v = \frac{135,75}{1,5} = \frac{1357,5}{15} = \frac{13575}{150} = 90,5](https://tex.z-dn.net/?f=v%20%3D%20%5Cfrac%7B135%2C75%7D%7B1%2C5%7D%20%3D%20%5Cfrac%7B1357%2C5%7D%7B15%7D%20%3D%20%5Cfrac%7B13575%7D%7B150%7D%20%3D%2090%2C5)
Ella condujo a una velocidad media de 90,5 km/h.
