limit as x approaches-4 of x^3+4x^2-8x

x \to - 4 lim (x^{3} + 4 x^{2} - 8 x)

32

Solution steps

x \to - 4 lim (x^{3} + 4 x^{2} - 8 x)

Plug in the value

x = - 4

= (- 4)^{3} + 4 (- 4)^{2} - 8 (- 4)

Simplify

(- 4)^{3} + 4 (- 4)^{2} - 8 (- 4) : 32

= 32

y ln (y) d x + (x - ln (y)) d y = 0

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

\frac{d y}{d x} = 1 - 2 y

\int tan^{5} (8 x) sec^{4} (8 x) d x

f (x) = \frac{1}{3 x}
