limit as x approaches 3 of (7x^2-3x)/x

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

18

Solution steps

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

Plug in the value

x = 3

= \frac{7 \cdot 3 ^{2} - 3 \cdot 3}{3}

Simplify

\frac{7 \cdot 3 ^{2} - 3 \cdot 3}{3} : 18

= 18

\frac{1}{4} (\frac{d y}{d t}) + 10 y = 5

\int sec^{2} (x t a) n^{2} x d x

f (x) = x^{3} - \frac{3}{2} x^{2} + x, at x = 1

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

\int 4 + y^{2} d y
