limit as x approaches-1 of 2x^2-5x-1

x \to - 1 lim (2 x^{2} - 5 x - 1)

6

Solution steps

x \to - 1 lim (2 x^{2} - 5 x - 1)

Plug in the value

x = - 1

= 2 (- 1)^{2} - 5 (- 1) - 1

Simplify

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

= 6

n = 0 \sum \infty \frac{4}{3 ^{n}}

\frac{d}{d x} (a x + b x + a y (x) + b y (x))
