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

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

- \infty

Solution steps

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

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

= 2 \cdot x \to 3 - lim (\frac{x}{x - 3})

Divide by highest denominator power:

\frac{1}{1 - \frac{3}{x}}

= 2 \cdot x \to 3 - lim (\frac{1}{1 - \frac{3}{x}})

For

x

approaching

3

from the left

, x < 3 \Rightarrow 1 - \frac{3}{x} < 0

The denominator is a negative quantity approaching 0 from the left

= 2 (- \infty)

Apply Infinity Property:

c \cdot (- \infty) = - \infty

= - \infty

x \to 3 lim (lo g_{5} (x))

\frac{d}{d x} (x + y)

sin (t)

x \to 0 + lim (e^{x})

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