The correct answer is:
$14 !$
Given,
$f(x)=\left(x^2-1\right)^7$
When we expand above expansion it will give one term of $x^{14}$ whose coefficient is 1 .
$\therefore \quad f^{14}(x)=14 !$
$f(x)=\left(x^2-1\right)^7$
When we expand above expansion it will give one term of $x^{14}$ whose coefficient is 1 .
$\therefore \quad f^{14}(x)=14 !$
