QuestionDetermine the domain on which the following function is decreasing.

Studdy Solution
Determine the interval where the function is decreasing:
- Since the function is a parabola that opens downwards, it decreases for $x$ values greater than the vertex. - Therefore, the function is decreasing for $x > 7$.
The domain on which the function is decreasing is:
$$\boxed{(7, \infty)}$$
