what is the internal notation of this graph? 

The graph in the image appears to be of a trigonometric function, likely a sine or cosine function, based on the sinusoidal shape.

The function seems to be of the form \( y = A \sin(Bx + C) + D \) or \( y = A \cos(Bx + C) + D \). The internal notation, also known as the interval notation, isn't directly determined by the graph itself but by the range of values that the function takes.

### Determining the Internal Notation:
1. **Amplitude (A):** The amplitude is the distance from the middle of the wave (mean value) to the peak. Based on the image, if the wave reaches a maximum of about 2 and a minimum of about -2, the amplitude \( A \) would be 2.
   
2. **Period (B):** The period of the function is the distance over which the function repeats. For a sine or cosine function, the period \( T \) is \( \frac{2\pi}{B} \).

3. **Phase Shift (C):** This determines the horizontal shift of the function. If the function starts from the origin and moves to the right, the phase shift would be positive.

4. **Vertical Shift (D):** This moves the function up or down on the graph.

### Interval Notation for Range:
If the graph's vertical extent is from \( -2 \) to \( 2 \), then the range in interval notation would be:

\[
[-2, 2]
\]

This indicates that the function's output (y-values) spans from -2 to 2.

If you meant interval notation for the domain (x-values), that would typically be all real numbers for sine and cosine functions, expressed as:

\[
(-\infty, \infty)
\]
