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

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

197

Solution steps

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

Plug in the value

x = - 4

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

Simplify

(- 4)^{4} + (- 4)^{3} - (- 4) + 1 : 197

= 197

x \to 3 lim (\frac{2 x + 5}{x - 3})

x \to 0 lim (\frac{3 x}{4 - x ^{2}})

x \to - 4 lim (x^{2} + 5 x + 4)

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

x \to 1 lim (ln (6 x) + e^{x})
