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, $$ f(-1) = -2 $$.**
$$ f(-1) = -2 $$

If \( f(x)=4 x+2, g(x)=2 x^{2}+7 x+2 \), and \( h(x)=8 x^{2}+6 \), find \( f(-1) \)
