Answer 1

1. f'(x) = 6 x² - 8x - 5
f'(2) = 6·(2)² - 8·2 - 5
f'(2) = 24 - 16 - 5
f'(2) = 26 - 21
f'(2) = 5
2. $\frac{3 x +1}{2 \sqrt{ x + 1}}$
f'(3) = $\frac{3*3 + 1}{2 \sqrt{3+1} }$
f'(3) = $\frac{10}{4}$
f'(3) = 2$\frac{1}{2}$
3. $f'(x) = \frac{2 - x}{2 \sqrt{x-1} * x^{2} }$
f'(2) = $\frac{2}{8 \sqrt{3} }$
4. f'(x) = 6t² - 3t·$e^{3t}$
f'(0) = 0
5. $f'(x) = - \frac{2}{ x^{2} -1}$
f'($\sqrt{3}$) = -$\frac{2}{ \sqrt{3} ^{2} -1}$
f'($\sqrt{3}$) = - $\frac{2}{4}$
f'($\sqrt{3}$) - $\frac{1}{2}$
