Evaluate the Function f(x)=3x+2 when x=-4

$f (x) = 3 x + 2$ when $x = - 4$

Replace the variable $x$ with $- 4$ in the expression.

$f (- 4) = 3 (- 4) + 2$

Simplify the result.

Multiply $3$ by $- 4$ .

$f (- 4) = - 12 + 2$

Add $- 12$ and $2$ .

$f (- 4) = - 10$

The final answer is $- 10$ .

$- 10$
