### Image and Preimage Calculation Using a Transformation Function

#### Transformation Function

We are provided with a transformation function \( T(v_1, v_2) \):

\[ 
T(v_1, v_2) = \left(\frac{\sqrt{2}}{2}v_1 - \frac{\sqrt{2}}{2}v_2, v_1 + v_2, 2v_1 - v_2 \right)
\]

#### Given Vectors

- **Vector \( \mathbf{v} \)**:
  \[
  \mathbf{v} = (2, 2)
  \]

- **Vector \( \mathbf{w} \)**:
  \[
  \mathbf{w} = \left(-6\sqrt{2}, 0, -18\right)
  \]

### Problem Statements

**(a) The Image of \( \mathbf{v} \)**

The image of vector \( \mathbf{v} \) under the transformation is:

\[ 
(0, 4, 2)
\]

This solution is verified as correct with a check mark.

**(b) The Preimage of \( \mathbf{w} \)**

The preimage of vector \( \mathbf{w} \) is:

\[ 
(2, 36)
\]

This solution is marked incorrect with a cross.

**Note:** If the vector has an infinite number of solutions, express your answer in terms of the parameter \( t \).
