Questions: Find the value C(-2), where C is defined below. C(t)=t^2-2t-4 Provide your answer below: C(-2)=

Find the value of \( C(-2) \) using the given function \( C(t) = t^{2} - 2t - 4 \).

Substitute \( t = -2 \) into the function.

\[ C(-2) = (-2)^{2} - 2(-2) - 4 \]

Calculate each term separately.

\[ (-2)^{2} = 4, \quad -2(-2) = 4, \quad -4 = -4 \]

Combine the results.

\[ C(-2) = 4 + 4 - 4 = 4 \]

\[ \boxed{C(-2) = 4} \]

The value of \( C(-2) \) is \(\boxed{4}\).
