limit as x approaches-1 of 3x^4-2x^3+4x

x \to - 1 lim (3 x^{4} - 2 x^{3} + 4 x)

1

Solution steps

x \to - 1 lim (3 x^{4} - 2 x^{3} + 4 x)

Plug in the value

x = - 1

= 3 (- 1)^{4} - 2 (- 1)^{3} + 4 (- 1)

Simplify

3 (- 1)^{4} - 2 (- 1)^{3} + 4 (- 1) : 1

= 1

\frac{\partial}{\partial x} (ln (1 + z) + x y^{2} + z)

\frac{1}{2 s ^{3} + 10 s ^{2} + 12 s}

y = x^{4} cos (4 x^{2})

y = 17 x, y = x^{2}

\int sin^{2} (t) cos (t) d t
