---

**Graph Analysis:**

The graph illustrates the derivative \( g'(x) \).

**Mathematical Context:**

Let \( f \) be the function given by \( f(x) = (\ln x)(\sin x) \). The figure below shows the graph of \( f \) for \( 0 < x \leq 2\pi \).

The function \( g \) is defined by:

\[ g(x) = \int_{1}^{x} f(t) \, dt \]

for \( 0 < x \leq 2\pi \).

**Note:** \( g'(x) = f(x) \)

---

**Question 14:**

On what intervals, if any, is \( g \) increasing? Justify your answer.

---

**Graph Description:**

- The graph starts at \( x = 0 \) and ends around \( x = 6 \).
- It shows an oscillating behavior with peaks and troughs, indicating where the function \( f(x) \) is positive or negative.
- The graph crosses the x-axis, indicating points where \( f(x) = 0 \).

**Meaning in Context:**

- The function \( g \) is increasing where \( f(x) \) (or \( g'(x) \)) is positive. This corresponds to intervals where the graph lies above the x-axis.

This material helps understand the behavior of integrals and derivatives in calculus, focusing on the increasing nature of functions defined by integrals.
