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

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

59

Solution steps

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

Plug in the value

x = - 2

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

Simplify

3 (- 2)^{4} + 2 (- 2)^{2} - (- 2) + 1 : 59

= 59

y^{^{''}} - 4 y^{^{'}} + 4 y = t^{3}, y (0) = 1, y^{^{'}} (0) = 0

\frac{d y}{d x} = \frac{( y - x + 1 )}{y - x - 6}

y^{^{''''}} + 5 y^{^{''}} + 4 y = 0, y (0) = 0

y d x - 4 x d y = y^{6}

\int \frac{x ^{3}}{3} \frac{1}{x} d x
