Step 2.2.1

Raise $2$ to the power of $4$ .

$f (2) = 3 \cdot 16 + {(2)}^{3} - 2 {(2)}^{2} + 2 + 12$

Step 2.2.2

Multiply $3$ by $16$ .

$f (2) = 48 + {(2)}^{3} - 2 {(2)}^{2} + 2 + 12$

Step 2.2.3

Raise $2$ to the power of $3$ .

$f (2) = 48 + 8 - 2 {(2)}^{2} + 2 + 12$

Step 2.2.4

Raise $2$ to the power of $2$ .

$f (2) = 48 + 8 - 2 \cdot 4 + 2 + 12$

Step 2.2.5

Multiply $- 2$ by $4$ .

$f (2) = 48 + 8 - 8 + 2 + 12$

Step 2.3

Simplify by adding and subtracting.

Step 2.3.1

Add $48$ and $8$ .

$f (2) = 56 - 8 + 2 + 12$

Step 2.3.2

Subtract $8$ from $56$ .

$f (2) = 48 + 2 + 12$

Step 2.3.3

Add $48$ and $2$ .

$f (2) = 50 + 12$

Step 2.3.4

Add $50$ and $12$ .

$f (2) = 62$

Step 2.4

The final answer is $62$ .
