Evaluate the Function c(-2)=t^2-2t-4

$c (- 2) = t^{2} - 2 t - 4$

Step 1

Replace the variable $t$ with $- 2$ in the expression.

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

Step 2

Simplify the result.

Simplify each term.

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

$c (- 2) = 4 - 2 \cdot - 2 - 4$

Multiply $- 2$ by $- 2$ .

$c (- 2) = 4 + 4 - 4$

Simplify by adding and subtracting.

Add $4$ and $4$ .

$c (- 2) = 8 - 4$

Subtract $4$ from $8$ .

$c (- 2) = 4$

The final answer is $4$ .

$4$
