limit as x approaches-2 of 3x^3-2x+7

x \to - 2 lim (3 x^{3} - 2 x + 7)

- 13

Solution steps

x \to - 2 lim (3 x^{3} - 2 x + 7)

Plug in the value

x = - 2

= 3 (- 2)^{3} - 2 (- 2) + 7

Simplify

3 (- 2)^{3} - 2 (- 2) + 7 : - 13

= - 13

\int \frac{1}{t - 20} d t

\int \frac{1}{1 + e ^{- 5 x}} d x

\frac{d}{d x} (sin^{2 x} (x))

\frac{d}{d x} ((sin (4 x))^{6 x})

cos (2 x^{3})
