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

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

1

Solution steps

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

Plug in the value

x = - 1

= (- 1)^{2} - 1 + 1

Simplify

(- 1)^{2} - 1 + 1 : 1

= 1

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

\frac{d}{d t} (e^{3 t})

x \to - 4 lim (- 7)

6 e^{- 2 t}

\frac{d}{d y} (ln (cos (\frac{x}{y ^{2}})))
