limit as x approaches-4 of sqrt(5x+20)-8

x \to - 4 lim (5 x + 20 - 8)

- 8

Solution steps

x \to - 4 lim (5 x + 20 - 8)

Plug in the value

x = - 4

= 5 (- 4) + 20 - 8

Simplify

5 (- 4) + 20 - 8 : - 8

= - 8

\int \frac{1}{2} (x + \frac{1}{2} sin (2 x)) d x

x \to 1 lim (x^{2} - 2 x)

\frac{\partial}{\partial y} (x^{2} - 5 x y + 3 y^{2})

x \to - 2 lim ((2 x - 1)^{2})

\int 4 x^{2} - 16 x + 16 d x
