The question is asking for the value of the expression \( 9y^2 - y - 8 \) when \( y = 2 \).

Let's solve it step-by-step:

1. Substitute \( y = 2 \) into the expression:
   \[
   9(2)^2 - 2 - 8
   \]

2. Calculate \( (2)^2 \):
   \[
   (2)^2 = 4
   \]

3. Multiply by 9:
   \[
   9 \times 4 = 36
   \]

4. Substitute back:
   \[
   36 - 2 - 8
   \]

5. Perform the remaining operations:
   - \( 36 - 2 = 34 \)
   - \( 34 - 8 = 26 \)

So, the correct answer is **26**, not 8454.
