Question

determine the domain on which the following graph of f(x) is positive.

Explanation:

Step1: Identify positive - y region

The function \(y = f(x)\) is positive when \(y>0\), which means the part of the graph above the x - axis.

Step2: Determine x - values

By observing the graph, the x - values for which the graph is above the x - axis are in the interval \((1,5)\).

Answer:

\((1,5)\)
