limit as x approaches 18 of (x^2)/2-9/x

x \to 18 lim (\frac{x ^{2}}{2} - \frac{9}{x})

\frac{323}{2}

Decimal Notation

161.5

Solution steps

x \to 18 lim (\frac{x ^{2}}{2} - \frac{9}{x})

Plug in the value

x = 18

= \frac{1 8 ^{2}}{2} - \frac{9}{18}

Simplify

\frac{1 8 ^{2}}{2} - \frac{9}{18} : \frac{323}{2}

= \frac{323}{2}

y^{^{'}} = 2 (3 x + y)^{2} - 1

\int_{1}^{2} \frac{x + 2 x ^{2}}{x} d x

n = 2 \sum \infty \frac{1}{n + 1}

\int - sin (2 x) d x

\int \frac{4 x}{x + 3} d x
