limit as x approaches 3 of-4x^3+2x+12

x \to 3 lim (- 4 x^{3} + 2 x + 12)

- 90

Solution steps

x \to 3 lim (- 4 x^{3} + 2 x + 12)

Plug in the value

x = 3

= - 4 \cdot 3^{3} + 2 \cdot 3 + 12

Simplify

- 4 \cdot 3^{3} + 2 \cdot 3 + 12 : - 90

= - 90

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

x \to \infty lim (\frac{x}{30})

x \to 0 lim (\frac{1 2 ^{x} - 1 3 ^{x}}{x})

x \to 0 lim (\frac{sin ( 10 x )}{sin ( 8 x )})

x \to 0 lim ((cos (x))^{(\frac{1}{x})^{2}})
