Evaluate the Function f(x)=-2x-5 for x=3

$f (x) = - 2 x - 5$ for $x = 3$

Step 1

Replace the variable $x$ with $3$ in the expression.

$f (3) = - 2 \cdot 3 - 5$

Step 2

Simplify the result.

Multiply $- 2$ by $3$ .

$f (3) = - 6 - 5$

Subtract $5$ from $- 6$ .

$f (3) = - 11$

The final answer is $- 11$ .

$- 11$
