limit as x approaches-1 of (x^2-4)/(1-x)

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

- \frac{3}{2}

Decimal Notation

- 1.5

Solution steps

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

Plug in the value

x = - 1

= \frac{( - 1 ) ^{2} - 4}{1 - ( - 1 )}

Simplify

\frac{( - 1 ) ^{2} - 4}{1 - ( - 1 )} : - \frac{3}{2}

= - \frac{3}{2}

\frac{d}{d x} (\frac{1}{- x})

\frac{d y}{d x} = 2 x y^{- 2}

f (x) = a^{8} + cos^{8} (x)

\int \frac{1}{1 + 121 x ^{2}} d x

7 x e^{6 x}
