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

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

16

Solution steps

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

Plug in the value

x = - 2

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

Simplify

- (- 2)^{4} + 8 (- 2)^{2} : 16

= 16

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

x \to 0 lim (\frac{1 + x}{1 - x})

x \to 0 lim (x + cos (x))

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

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