## Mathematics Practice Problems

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

The given graph is a parabola opening upwards. Use the options below to determine the correct equation.

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 vertex of the parabola appears to be at \((-2, -3)\).

### 6. Graph \( f(x) = \sqrt{x + 2} - 3 \)

**Graph:**
- This is the plot of a transformed square root function.

### 7. & 8. Use the following functions for #7, 8. Let \( f(x) = 2x^2 + 3x \) and \( g(x) = x^2 + 4x \).

7. Find \( (f \circ g)(5) \)

**Answer:** ______________________

8. Find \( (f \circ g)(2) \)

**Answer:** ______________________

### 9. Let \( f(x) = 3x - 2 \) and \( g(x) = -x + 4 \). Find \( (f \circ g)(5) \).

**Answer:** ______________________

### 10. Let \( f(x) = 3x + 4 \) and \( g(x) = x^2 \). Find \( (f \circ g)(x) \) and its domain.

**Answer:** _____________________________________________________

---

**Graph Explanations:**

- **Graph in #5:** The graph provided is a parabola. By observing the vertex and comparing the given options, you should identify the correct parabola equation.
- **Graph in #6:** The function \( f(x) = \sqrt{x + 2} - 3 \) is a square root function translated. The graph should shift left by 2 units and down by 3 units.

Ensure to solve each problem step by step, plugging in values as needed, and making sure you understand the transformations of functions when graphing
