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

$f (- 3) = - 2 x^{3} - 5$

Step 1

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

$f (- 3) = - 2 {(- 3)}^{3} - 5$

Step 2

Simplify the result.

Simplify each term.

Raise $- 3$ to the power of $3$ .

$f (- 3) = - 2 \cdot - 27 - 5$

Multiply $- 2$ by $- 27$ .

$f (- 3) = 54 - 5$

Subtract $5$ from $54$ .

$f (- 3) = 49$

The final answer is $49$ .

$49$
