limit as x approaches-2 of 3x^2+7-1/x

x \to - 2 lim (3 x^{2} + 7 - \frac{1}{x})

\frac{39}{2}

Decimal

19.5

Solution steps

x \to - 2 lim (3 x^{2} + 7 - \frac{1}{x})

Plug in the value

x = - 2

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

Simplify

3 (- 2)^{2} + 7 - \frac{1}{- 2} : \frac{39}{2}

= \frac{39}{2}

\int \frac{1}{1 + ( cos ( x ) ) ^{2}} d x

\frac{d}{d x} (\frac{18 x + 4 x ^{2}}{( 9 + 4 x ) ^{2}})

\int_{0}^{1} 2 + 1 - x^{2} d x

\frac{d}{d x} ((1 + x)^{\frac{1}{x}})

\int sin (t^{2}) d t
