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

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

7

Solution steps

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

Plug in the value

x = - 2

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

Simplify

\frac{( - 2 ) ^{3} + 1}{- 2 + 1} : 7

= 7

y^{^{''}} - 3 y^{^{'}} + 2 y = 14 sin (2 x) + 18 cos (2 x)

\frac{d}{d x} (3 x^{5} - 2 x^{4} - 4 x^{3})

(y - x^{2} + y^{2}) d x - x d y = 0

\frac{d}{d x} (x ln (x^{6}))

f (x) = 110 x - 16 x^{2}, at 3
