**Title: Analyzing Critical Points and Local Minima from a Derivative Graph**

**Content:**

2) Suppose \( g \) is a continuous function on the interval \((-5, 4)\). The graph of \( g' \), the derivative of \( g \), is given in the figure below.

**Graph Analysis:**

The graph displays the derivative \( g' \) of the function \( g \) over the interval \((-5, 4)\). The graph can be described as follows:

- From \( x = -5 \) to \( x = -3 \), the graph rises, crossing the x-axis at \( x = -4 \). 
- From \( x = -3 \) to \( x = 1 \), the graph decreases, crossing the x-axis at \( x = -1 \).
- From \( x = 1 \) to \( x = 4 \), the graph increases again, crossing the x-axis at \( x = 3 \).

Noticeable points on the graph include:
- Peaks or valleys where the curve changes direction (possible critical points).
- Intervals where the derivative \( g' \) is positive (function \( g \) increases).
- Intervals where the derivative \( g' \) is negative (function \( g \) decreases).

**Exercises:**

a) **List all the critical points (if any) of \( g \) in the interval \((-5, 4)\). Write "NONE" if appropriate.**

   \[
   x = \_\_\_\_\_\_\_\_\_\_\_\_
   \]

b) **At what point (or points) does the function \( g \) have a local minimum? Write "NONE" if appropriate.**

   \[
   x = \_\_\_\_\_\_\_\_\_\_\_\_
   \]

**Guidance for Answering:**

- **Critical Points:** Critical points occur where the derivative \( g' \) is zero or undefined. Observe where the graph crosses the x-axis.
- **Local Minima:** A local minimum can occur at a critical point where \( g' \) changes from negative to positive. Analyze the intervals of positivity and negativity in the graph of \( g' \).
