Evaluate f(x)=4(-3)^2-(-3)-3

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

Step 1

Simplify $4 {(- 3)}^{2} - (- 3) - 3$ .

Simplify each term.

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

$f (x) = 4 \cdot 9 - (- 3) - 3$

Multiply $4$ by $9$ .

$f (x) = 36 - (- 3) - 3$

Multiply $- 1$ by $- 3$ .

$f (x) = 36 + 3 - 3$

$f (x) = 36 + 3 - 3$

Simplify by adding and subtracting.

Add $36$ and $3$ .

$f (x) = 39 - 3$

Subtract $3$ from $39$ .

$f (x) = 36$

$f (x) = 36$

$f (x) = 36$

Step 2

Subtract $f (x)$ from both sides of the equation.

$0 = 36 - f (x)$

Step 3

Rewrite the equation as $36 - f (x) = 0$ .

$36 - f (x) = 0$
