limit as x approaches-2 of 2x^3-x^2+4x+1

x \to - 2 lim (2 x^{3} - x^{2} + 4 x + 1)

- 27

Solution steps

x \to - 2 lim (2 x^{3} - x^{2} + 4 x + 1)

Plug in the value

x = - 2

= 2 (- 2)^{3} - (- 2)^{2} + 4 (- 2) + 1

Simplify

2 (- 2)^{3} - (- 2)^{2} + 4 (- 2) + 1 : - 27

= - 27

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

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

x \to 3 + lim (\frac{x}{x ^{2} - 9})

x \to 0 lim ((5 x)^{s i n (x)})

x \to 0 lim (cos^{\frac{1}{c o s ( x ) - c o s ( 7 x )}} (4 x))
