$$\int\limits_{-1}^{0} \left(- \frac{1}{\sqrt{3 x + 4}}\right)\, dx$$

Integral(-1/sqrt(3*x + 4), (x, -1, 0))

Detail solution

The integral of a constant times a function is the constant times the integral of the function:

$\int \left(- \frac{1}{\sqrt{3 x + 4}}\right)\, dx = - \int \frac{1}{\sqrt{3 x + 4}}\, dx$
1. Let $u = \sqrt{3 x + 4}$ .
  
  Then let $du = \frac{3 dx}{2 \sqrt{3 x + 4}}$ and substitute $\frac{2 du}{3}$ :
  
  $\int \frac{2}{3}\, du$
  1. The integral of a constant times a function is the constant times the integral of the function:
    
    $\text{False}$
    1. The integral of a constant is the constant times the variable of integration:
      
      $\int 1\, du = u$
    So, the result is: $\frac{2 u}{3}$
  Now substitute $u$ back in:
  
  $\frac{2 \sqrt{3 x + 4}}{3}$
So, the result is: $- \frac{2 \sqrt{3 x + 4}}{3}$
Now simplify:

$- \frac{2 \sqrt{3 x + 4}}{3}$
Add the constant of integration:

$- \frac{2 \sqrt{3 x + 4}}{3}+ \mathrm{constant}$

The answer is:

$- \frac{2 \sqrt{3 x + 4}}{3}+ \mathrm{constant}$
