The equation \( V = \frac{4}{3}\pi r^3 \) describes the volume of a sphere in terms of its radius \( r \). As the radius \( r \) increases, the volume \( V \) also increases, specifically in proportion to the cube of the radius.
The end behavior of the equation can be summarized as follows:
- As the radius \( r \) increases to infinity, the volume \( V \) increases to infinity.
So the correct response is:
As the radius increases to infinity, the volume of the sphere will increase to infinity.
