limit as x approaches-3 of x^4+3x+9

x \to - 3 lim (x^{4} + 3 x + 9)

81

Solution steps

x \to - 3 lim (x^{4} + 3 x + 9)

Plug in the value

x = - 3

= (- 3)^{4} + 3 (- 3) + 9

Simplify

(- 3)^{4} + 3 (- 3) + 9 : 81

= 81

\int \frac{x + 4}{x ^{2} + 16} d x

y^{^{''}} - 5 y^{^{'}} + 6 y = e^{t}

\int_{0}^{1} 9 t^{4} + 4 t^{2} d t

\int_{1}^{4} (x^{2} + x) d x

\frac{d}{d x} (- x^{- 2})
