limit as x approaches-3 of-x^2+8x-9

x \to - 3 lim (- x^{2} + 8 x - 9)

- 42

Solution steps

x \to - 3 lim (- x^{2} + 8 x - 9)

Plug in the value

x = - 3

= - (- 3)^{2} + 8 (- 3) - 9

Simplify

- (- 3)^{2} + 8 (- 3) - 9 : - 42

= - 42

\int \frac{1}{x ^{2}} sin (\frac{π}{x}) d x

\frac{d}{d x} (9 x e^{2 x})

y = x^{2} - 2 x - 2, (2, - 2)

\frac{1}{s ^{2} - 6 s + 9}

\int 22 arctan (x) d x
