Answer
\( f(-1) = -2 \)
Solution
To find \( f(-1) \) for the function \( f(x) = 4x + 2 \), follow these steps:
1. **Substitute \(-1\) for \(x\) in the function:**
\[
f(-1) = 4(-1) + 2
\]
2. **Perform the multiplication:**
\[
4(-1) = -4
\]
3. **Add the constant term:**
\[
-4 + 2 = -2
\]
**Therefore, \( f(-1) = -2 \).**

To find \( f(-1) \), we need to substitute \( -1 \) into the function \( f(x) = 4x + 2 \). So we calculate: \[ f(-1) = 4(-1) + 2 \] \[ f(-1) = -4 + 2 \] \[ f(-1) = -2 \] Thus, \( f(-1) = -2 \).
