limit as x approaches-1 of 3x^2-2x-1

x \to - 1 lim (3 x^{2} - 2 x - 1)

4

Solution steps

x \to - 1 lim (3 x^{2} - 2 x - 1)

Plug in the value

x = - 1

= 3 (- 1)^{2} - 2 (- 1) - 1

Simplify

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

= 4

f (x) = 3 - x^{2} + 2 x

f (x) = 8 x^{2} + 4 x - 6, at x = - 3

\int \frac{u - 2 u ^{2}}{u} d u

\int a e^{x} d x

\int \frac{8}{e ^{x} - 2} d x
