1. Given w(n) = n - 1 find the value of the function if = -1.

2. Given f(x) = ||x|| - 3 find f(9.3) .

3. Evaluate the function w(x) = |- 2x + 3| if x = - 1

4. Evaluate: f(x) = - x - 1 find f(a ^ 2)

5. Given f(x) = 4x - 5 find f' * (2x + 3)

Let's solve each of the given problems one by one.

### 1. Given \( w(n) = n - 1 \), find the value of the function if \( n = -1 \).

\[ w(-1) = -1 - 1 = -2 \]

So, the value of \( w(-1) \) is \(-2\).

### 2. Given \( f(x) = \|x\| - 3 \), find \( f(9.3) \).

Here, \(\|x\|\) represents the absolute value of \(x\).

\[ f(9.3) = |9.3| - 3 =
