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

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

9

Solution steps

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

Plug in the value

x = - 2

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

Simplify

4 (- 2)^{2} + 3 (- 2) - 1 : 9

= 9

\int (6 x^{2} - 3 x + 5) d x

(- 1, 2), (1, - 1)

\int 2 x^{5} y + 3 x^{4} y^{2} d y

\frac{\partial}{\partial x} (x yz)

\int e^{- 2 x} (1 - 2 x) d x
