Evaluate the Function f(4)=-3x-1

$f (4) = - 3 x - 1$

Step 1

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

$f (4) = - 3 \cdot 4 - 1$

Step 2

Simplify the result.

Multiply $- 3$ by $4$ .

$f (4) = - 12 - 1$

Subtract $1$ from $- 12$ .

$f (4) = - 13$

The final answer is $- 13$ .

$- 13$
