Evaluate the Function A(4)=2x^3+5

$A (4) = 2 x^{3} + 5$

Step 1

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

$A (4) = 2 {(4)}^{3} + 5$

Step 2

Simplify the result.

Simplify each term.

Raise $4$ to the power of $3$ .

$A (4) = 2 \cdot 64 + 5$

Multiply $2$ by $64$ .

$A (4) = 128 + 5$

Add $128$ and $5$ .

$A (4) = 133$

The final answer is $133$ .
