limit as x approaches-1 of (x^3-8)/(x-2)

x \to - 1 lim (\frac{x ^{3} - 8}{x - 2})

3

Solution steps

x \to - 1 lim (\frac{x ^{3} - 8}{x - 2})

Plug in the value

x = - 1

= \frac{( - 1 ) ^{3} - 8}{- 1 - 2}

Simplify

\frac{( - 1 ) ^{3} - 8}{- 1 - 2} : 3

= 3

\frac{d}{d x} (5 x^{\frac{4}{3}})

\frac{d}{d x} (\frac{5 x ^{2}}{3 x - 1})

\int \frac{1}{x 16 + x ^{2}} d x

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

\int x^{3} sin (n x) d x
