limit as x approaches-1 of-2x^3+3x^2+x+1

x \to - 1 lim (- 2 x^{3} + 3 x^{2} + x + 1)

5

Solution steps

x \to - 1 lim (- 2 x^{3} + 3 x^{2} + x + 1)

Plug in the value

x = - 1

= - 2 (- 1)^{3} + 3 (- 1)^{2} - 1 + 1

Simplify

- 2 (- 1)^{3} + 3 (- 1)^{2} - 1 + 1 : 5

= 5

x \to - 1 - lim (x + 1)

x \to 0 lim (xx)

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

x \to 2 lim (6 x - 2)

x \to 0 lim (\frac{4}{x} sin (\frac{x}{5}))
