limit as x approaches 4-of (1-x)/(4-x)

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

- \infty

Solution steps

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

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

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

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

x \to 4 - lim (1 - x) = - 3

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

= (- 3) \cdot \infty

Apply Infinity Property:

- c \cdot \infty = - \infty

= - \infty

\int x ln (9 x) d x

x \to 2 lim (x^{2} + 4)

\frac{d}{d x} (x e^{c o s (2 x - y)})

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

\frac{\partial}{\partial y} (x^{3} + x^{2} y - y^{2} - 4 y)
