Answer 1

To find \( f(-2) \) for the function \( f(x) = 3x + 8 \), follow these steps:

1. Substitute \( -2 \) for \( x \) in the function: \[ f(-2) = 3(-2) + 8 \]

2. Calculate \( 3(-2) \): \[ 3(-2) = -6 \]

3. Add \( 8 \) to \( -6 \): \[ f(-2) = -6 + 8 \]

4. Compute the final result: \[ -6 + 8 = 2 \]

Thus, \[ f(-2) = 2. \]
