limit as x approaches-2 of-x^2+4x-1

x \to - 2 lim (- x^{2} + 4 x - 1)

- 13

Solution steps

x \to - 2 lim (- x^{2} + 4 x - 1)

Plug in the value

x = - 2

= - (- 2)^{2} + 4 (- 2) - 1

Simplify

- (- 2)^{2} + 4 (- 2) - 1 : - 13

= - 13

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

\frac{d}{d x} (- 3 x)

\int 10 - e^{2 x} d x

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

\frac{d P}{d t} = Pt, P (1) = 3
