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

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

Step 1

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

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

Step 2

Simplify the result.

Simplify each term.

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

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

Multiply $3$ by $- 27$ .

$f (- 3) = - 81 + 5$

Add $- 81$ and $5$ .

$f (- 3) = - 76$

The final answer is $- 76$ .

$- 76$
