Question
**Title: Sum, Difference, and Product of Two Functions**

**Overview:**

Suppose that the functions \( s \) and \( t \) are defined for all real numbers \( x \) as follows:

\[ s(x) = x + 3 \]

\[ t(x) = 4x - 6 \]

**Task:**

Write the expressions for \( (t+s)(x) \) and \( (t-s)(x) \) and evaluate \( (t \cdot s)(1) \).

**Expressions:**

1. \( (t+s)(x) = \) [Enter your answer here]

2. \( (t-s)(x) = \) [Enter your answer here]

3. \( (t \cdot s)(1) = \) [Enter your answer here]

**Note:**

To solve these problems, use the following operations:

- Addition: \( (t+s)(x) = t(x) + s(x) \)
- Subtraction: \( (t-s)(x) = t(x) - s(x) \)
- Multiplication: \( (t \cdot s)(1) = t(1) \cdot s(1) \)
