limit as x approaches 3-of (6x)/(x-3)

x \to 3 - lim (\frac{6 x}{x - 3})

- \infty

Solution steps

x \to 3 - lim (\frac{6 x}{x - 3})

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 - 3})

Divide by highest denominator power:

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

= 6 \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

= 6 (- \infty)

Apply Infinity Property:

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

= - \infty

\int sin (4 x - 7) d x

\int_{- 2}^{3} \frac{16}{x ^{4}} d x

f (x) = 6 x^{3}

\int 5 x^{2} - 7 x + 4 d x

(2 x + 2)^{\frac{1}{4}}
