The image you've uploaded contains some mathematical expressions and questions. I'll go ahead and extract the relevant information to help you with the problem.

The text from the image appears to focus on evaluating the function \( f(x) = x^2 + 3x - 4 \) at specific values of \( x \):

1. \( f(2) \)
2. \( f(-3) \)
3. \( f(0) \)

### Let's solve each one:

1. **Evaluate \( f(2) \):**

   Substitute \( x = 2 \) into the function \( f(x) = x^2 + 3x - 4 \):
   \[
   f(2) = (2)^2 + 3(2) - 4 = 4 + 6 - 4 = 6
   \]
   So, \( f(2) = 6 \).

2. **Evaluate \( f(-3) \):**

   Substitute \( x = -3 \) into the function \( f(x) = x^2 + 3x - 4 \):
   \[
   f(-3) = (-3)^2 + 3(-3) - 4 = 9 - 9 - 4 = -4
   \]
   So, \( f(-3) = -4 \).

3. **Evaluate \( f(0) \):**

   Substitute \( x = 0 \) into the function \( f(x) = x^2 + 3x - 4 \):
   \[
   f(0) = (0)^2 + 3(0) - 4 = 0 + 0 - 4 = -4
   \]
   So, \( f(0) = -4 \).

### Summary:
- \( f(2) = 6 \)
- \( f(-3) = -4 \)
- \( f(0) = -4 \)

4. How does the sign of the coefficient of \( x^2 \) affect the shape of the parabola for a quadratic function?
5. What are the vertex and axis of symmetry of the function \( f(x) = x^2 + 3x - 4 \)?

### Tip:
When evaluating a function at a specific point, always ensure that you carefully substitute the value into the equation and simplify step by step to avoid mistakes.
