### Quadratic Function Analysis

**Problem Statement:**

5. Determine the equation of the graph below. Choose the correct equation.

**Options:**
a) \( y = (x - 2)^2 + 3 \)  
b) \( y = (x - 2)^2 - 3 \)  
c) \( y = (x + 2)^2 + 3 \)  
d) \( y = (x + 2)^2 - 3 \)  

**Graph:**

The graph depicts a parabola opening upwards with its vertex appearing at the point \((-2, -3)\). The x-axis ranges from \(-6\) to \(6\), and the y-axis ranges from \(-6\) to \(6\).

### Explanation of the Graph:
- The parabola is a quadratic function in the standard form \( y = a(x - h)^2 + k \).
- The vertex form of a parabola is given by \( y = a(x - h)^2 + k \), where \( (h, k) \) is the vertex of the parabola.
- Based on the graph, the vertex of the parabola is \((-2, -3)\).

Considering the form of the vertex \( (h, k) \):

- The x-coordinate \( h \) is \(-2\),
- The y-coordinate \( k \) is \(-3\).

Thus, the equation of the parabola should be:  
\[ y = a(x + 2)^2 - 3 \]

Since the parabola opens upwards, the coefficient \( a \) is positive and specifically it is 1 here. Hence, the correct equation matching the vertex of \((-2, -3)\) is:

**Answer:**
\[ \boxed{d \: y = (x + 2)^2 - 3} \]
