limit as x approaches-1 of 2x^2+6x-1

x \to - 1 lim (2 x^{2} + 6 x - 1)

- 5

Solution steps

x \to - 1 lim (2 x^{2} + 6 x - 1)

Plug in the value

x = - 1

= 2 (- 1)^{2} + 6 (- 1) - 1

Simplify

2 (- 1)^{2} + 6 (- 1) - 1 : - 5

= - 5

x \to 2 lim (\frac{5}{∣ 2 - x ∣})

\frac{d}{d x} (e^{- \frac{x}{a}})

f (x) = e^{x} arctan (x)

2 sin (x) + sin^{2} (x)

\frac{d}{d x} (cot^{3} (x))
