QuestionFind the derivatives of these functions: 1. $f(x)=6 x^{3}-9 x+4$, 2. $y=2 t^{4}- t^{2}+13 t$, 3. $g(z)=4 z^{7}-3 z^{-7}+9 z$.

Studdy Solution
implify the expression to obtain the derivative of $g(z)$.
$$g'(z) =28z^{6} +21z^{-8} +9$$So, the derivatives of the given functions are. $f'(x) =18x^{2} -9$
2. $y'(t) =8t^{3} -2t +13$
3. $g'(z) =28z^{6} +21z^{-8} +9$
