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

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

66

Solution steps

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

Plug in the value

x = - 2

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

Simplify

3 (- 2)^{4} + 2 (- 2)^{2} - (- 2) + 8 : 66

= 66

x \to 0 lim (tan (x^{2} - x - 9))

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

x \to 9 lim (9 - x)

x \to 0 + lim (\frac{9}{x} - ln (x))

x \to 0 lim (\frac{3}{2 x})
