limit as x approaches 3+of (6x)/(x^2-9)

x \to 3 + lim (\frac{6 x}{x ^{2} - 9})

\infty

Solution steps

x \to 3 + lim (\frac{6 x}{x ^{2} - 9})

x \to a lim [c \cdot f (x)] = c \cdot x \to a lim f (x)

= 6 \cdot x \to 3 + lim (\frac{x}{x ^{2} - 9})

\frac{x}{x ^{2} - 9} = x \frac{1}{x ^{2} - 9}

= 6 \cdot x \to 3 + lim (x \frac{1}{x ^{2} - 9})

x \to a lim [f (x) \cdot g (x)] = x \to a lim f (x) \cdot x \to a lim g (x)

With the exception of indeterminate form

= 6 \cdot x \to 3 + lim (x) \cdot x \to 3 + lim (\frac{1}{x ^{2} - 9})

x \to 3 + lim (x) = 3

x \to 3 + lim (\frac{1}{x ^{2} - 9}) = \infty

= 6 \cdot 3 \cdot \infty

Apply Infinity Property:

c \cdot \infty = \infty

= \infty

t sin (t)

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

\int_{0}^{\infty} x^{2} d x

\int \frac{1}{x ^{2} + 7} d x

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