Transcribed Image Text:**Question:**
Find \( f'(t) \) if \( f(t) = 4t^2 + 8t + 3 \).
**Solution:**
To find the derivative \( f'(t) \), apply the power rule to each term in the function \( f(t) = 4t^2 + 8t + 3 \).
- The derivative of \( 4t^2 \) is \( 8t \) (using the power rule: \((at^n)' = nat^{n-1}\)).
- The derivative of \( 8t \) is \( 8 \) (since \((at)' = a\)).
- The derivative of the constant \( 3 \) is \( 0 \).
Thus, the derivative \( f'(t) = 8t + 8 \).
**Answer:**
\( f'(t) = 8t + 8 \)
