### Graphs of Trigonometric Functions

Three graphs are given below. Each graph corresponds to one of the following equations:

\[y = 2 + \csc x \]
\[y = \sec \left( x + \frac{\pi}{4} \right) \]
\[y = -\cot x \]
\[y = \sec x \]
\[y = \cot \left( x - \frac{\pi}{4} \right) \]
\[y = \tan x \]

Analyze each graph and choose the appropriate equation from the list provided.

**Graph Analysis**

#### First Graph
The first graph shows a periodic function with vertical asymptotes at intervals of \(\pi\). The graph has a maximum value at \(y = 2\) units above the x-axis and dips down sharply as it approaches the asymptotes.

**- Equation:** \( y = 2 + \csc x \)

#### Second Graph
The second graph demonstrates a function with vertical asymptotes repeating at \(\pi\) intervals. The graph pattern suggests that it's a secant function but shifted horizontally.

**- Equation:** \( y = \sec \left( x + \frac{\pi}{4} \right) \)

#### Third Graph
The third graph displays a periodic function also with vertical asymptotes. The pattern and symmetry indicate it represents a cotangent function.

**- Equation:** \(y = -\cot x\)

### Conclusion
Each graph corresponds to one of the trigonometric equations given. The equations matched to the graphs are as follows:
1. \( y = 2 + \csc x \)
2. \( y = \sec \left( x + \frac{\pi}{4} \right) \)
3. \( y = -\cot x\)

By analyzing the periodicity, asymptotes, and other characteristics, we can match each function to its graphical representation.
