determine the domain on which the following function is decreasing. answer attempt 4 out of 5 submit answer ∅ or ∪ ∞ < > ≤ ≥ , (,) (, ,) all real numbers

Answer

Explanation:

Step1: Understand function decrease

A function is decreasing when as $x$ increases, $y$ decreases.

Step2: Observe the graph

From the graph, we see the function starts decreasing after the vertex. The vertex appears to be at $x = 5$. As $x$ moves from $5$ to positive - infinity, the $y$ - values of the function are getting smaller.

Answer:

$(5,\infty)$
