limit as x approaches-1 of 1/(x^2)+3x-1

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

- 3

Solution steps

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

Plug in the value

x = - 1

= \frac{1}{( - 1 ) ^{2}} + 3 (- 1) - 1

Simplify

\frac{1}{( - 1 ) ^{2}} + 3 (- 1) - 1 : - 3

= - 3

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

x^{^{''}} + 25 x = 0

\frac{d}{d x} (e^{x} cos (x))

\frac{d}{d x} (ln (e^{x} + 7 x + 1))

\frac{\partial}{\partial r} (r \cdot cos (t))
