Question 5.
$$\frac{8 x+13}{\sqrt{4 x+7}}$$
Solution:

Question 6.
$$\frac{1}{\sqrt{x+1}+\sqrt{x-1}}$$
Solution:

Question 7.
If f'(x) = x + b, f(1) = 5 and f(2) = 13, then find f(x)
Solution:
f'(x) = x + b
Integrating both sides of the equations

Question 8.
If f(x) = 8x3 – 2x and f(2) = 8, then find f(x)
Solution:
f'(x) = 8x3 – 2x
Integrating both sides of the equation,
