Evaluate Using the Given Value f(4)=3(4)^2-2*4

$f (4) = 3 {(4)}^{2} - 2 \cdot 4$

Step 1

Simplify each term.

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

$f (4) = 3 \cdot 16 - 2 \cdot 4$

Multiply $3$ by $16$ .

$f (4) = 48 - 2 \cdot 4$

Multiply $- 2$ by $4$ .

$f (4) = 48 - 8$

Step 2

Subtract $8$ from $48$ .

$f (4) = 40$
