limit as x approaches 1 of 7-2x-x^2

x \to 1 lim (7 - 2 x - x^{2})

4

Solution steps

x \to 1 lim (7 - 2 x - x^{2})

Plug in the value

x = 1

= 7 - 2 \cdot 1 - 1^{2}

Simplify

= 4

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

\int x (x - 1) d x

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

\frac{\partial}{\partial x} (\frac{m \cdot x \cdot T}{A})

x \to 1 + lim (7 ∣ x + 1 ∣ - 4)
