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

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

- 42

Solution steps

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

Plug in the value

x = - 2

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

Simplify

4 (- 2)^{3} + 4 (- 2) - 2 : - 42

= - 42

8 - x^{2}, x^{2}, (- 3, 3)

\frac{1}{x + 1}

y^{^{''}} + 4 y^{^{'}} + 5 y = 10 x + 5 e^{- x}

3 x^{2}, - 3 x + 6

\int (sec^{2} (x) e^{t a n (x)}) d x
