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

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

3

Solution steps

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

Plug in the value

x = - 2

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

Simplify

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

= 3

y^{^{''}} + 8 y + 16 y = 0

n = 1 \sum \infty n e^{9 n}

\int (x + 1)^{- 1} d x

x + 3, \frac{x + 3}{2}

\frac{d y}{d x} = \frac{5 y}{x}
