limit as x approaches-3 of x^3+4x^2-7

x \to - 3 lim (x^{3} + 4 x^{2} - 7)

2

Solution steps

x \to - 3 lim (x^{3} + 4 x^{2} - 7)

Plug in the value

x = - 3

= (- 3)^{3} + 4 (- 3)^{2} - 7

Simplify

(- 3)^{3} + 4 (- 3)^{2} - 7 : 2

= 2

y^{^{''}} + 4 y = e^{- x} (7 - 4 x + 5 x^{2})

\frac{d y}{d x} = (y + 1) (y - 2), y (0) = 0

\frac{\partial}{\partial x} (6 ln (6 x^{3} + y^{2}))

g (t) = t^{3} cos (t)

\frac{d}{d x} (ln (2 x^{2} - 1))
