Let's go through each derivative problem in the file step-by-step:

1. $f(x) = \frac{2x - 3}{3x + 4}$

• Find $f'(x)$, $f'(1)$, and $f'\left(-\frac{4}{3}\right)$ if possible.

2. $f(x) = x^{\frac{1}{3}}$

• Find $f'(x)$, $f'(1)$, and $f'(0)$ if possible.

3. $f(x) = \sqrt{x^{23}}$

• Simplify and find $f'(x)$.

4. $f(x) = (5x^2 - 5)(4x + 2)$

• Use the product rule to find $f'(x)$.

5. $f(x) = \frac{x^3 + 1}{x^2 + 2(x^2 - 2x + 1)}$

• Differentiate the function.

6. $y = \left(\frac{3x^3 - 5x}{4x + 17}\right)^3$

• Use the chain rule and quotient rule to find $y'$.

7. $y = \frac{\sqrt{x^2 + 1}}{1 + \sqrt{x^2 + 1}}$

• Differentiate using the quotient and chain rules.

8. $y = x \sin x$

• Use the product rule to find $y'$.

9. $y = \frac{1 - \cos x}{1 + \cos x}$

• Differentiate using the quotient rule.

10. $y = \frac{\sin x \sec x}{1 + \tan x}$

• Use trigonometric identities and the quotient rule to find $y'$.
