limit as x approaches-2 of (3x-9)/(x+1)

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

15

Solution steps

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

Plug in the value

x = - 2

= \frac{3 ( - 2 ) - 9}{- 2 + 1}

Simplify

\frac{3 ( - 2 ) - 9}{- 2 + 1} : 15

= 15

n = 2 \sum \infty \frac{1}{( - 5 ) ^{n}}

n \to + 0 - lim (5 + \frac{4}{n})

\int 3 \cdot cos (3 x) d x

\int \frac{x ^{15}}{x ^{16} + 1} d x

\int 2 x (x^{2} + 2)^{7} d x
