limit as x approaches-1 of x^3+x^2-6x+9

x \to - 1 lim (x^{3} + x^{2} - 6 x + 9)

15

Solution steps

x \to - 1 lim (x^{3} + x^{2} - 6 x + 9)

Plug in the value

x = - 1

= (- 1)^{3} + (- 1)^{2} - 6 (- 1) + 9

Simplify

(- 1)^{3} + (- 1)^{2} - 6 (- 1) + 9 : 15

= 15

\int \frac{x}{( x + 2 ) ( 5 x - 1 )} d x

\frac{d ^{2}}{d x ^{2}} (tan (5 x + 2))

\int \frac{16 x}{( x ^{2} - 9 ) ^{5}} d x

y^{^{'}} = 2 y (1 - 0.2 y)

\int 4 \frac{1}{( 4 - x ^{2} ) ^{\frac{3}{2}}} d x
