limit as x approaches 4-of (x+5)/(x-4)

x \to 4 - lim (\frac{x + 5}{x - 4})

- \infty

Solution steps

x \to 4 - lim (\frac{x + 5}{x - 4})

\frac{x + 5}{x - 4} = (x + 5) \frac{1}{x - 4}

= x \to 4 - lim ((x + 5) \frac{1}{x - 4})

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

= x \to 4 - lim (x + 5) \cdot x \to 4 - lim (\frac{1}{x - 4})

x \to 4 - lim (x + 5) = 9

x \to 4 - lim (\frac{1}{x - 4}) = - \infty

= 9 (- \infty)

Apply Infinity Property:

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

= - \infty

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

x, y = 2, x = 0

\frac{\partial}{\partial x} (sin (x) + cos (y))

f (x) = \frac{x ^{3}}{x - 1}

n = 0 \sum \infty (\frac{2}{7})^{\frac{n}{2}}
