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

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

27

Solution steps

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

Plug in the value

x = 2

= 3 \cdot 2^{3} + 2 \cdot 2 - 1

Simplify

3 \cdot 2^{3} + 2 \cdot 2 - 1 : 27

= 27

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

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

x \to - 2 - lim (\frac{x ^{2}}{3 x + 6})

t \to 1 lim (t^{2})

x \to 4 lim (5 x + 2)
