Answer is: option2
\( -66 \)Solution:
\( f(x) = (g(x))^2 h(x) \)
\( f'(x) = (g(x))^2 h'(x) + h(x) \left[ 2g(x) g'(x) \right] \)
\( f'(-2) = (g(-2))^2 h'(-2) + h(-2) \left[ 2g(-2) g'(-2) \right] \)
\( f'(-2) = (-3)^2 (-4) + (1) \cdot \left( 2 \cdot (-3) \cdot (-5) \right) \)
\( f'(-2) = -36 - 30 \)
\( f'(-2) = -66 \, \text{Ans} \)
