limit as x approaches 7-of (x+8)/(x-7)

x \to 7 - lim (\frac{x + 8}{x - 7})

- \infty

Solution steps

x \to 7 - lim (\frac{x + 8}{x - 7})

\frac{x + 8}{x - 7} = (x + 8) \frac{1}{x - 7}

= x \to 7 - lim ((x + 8) \frac{1}{x - 7})

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 7 - lim (x + 8) \cdot x \to 7 - lim (\frac{1}{x - 7})

x \to 7 - lim (x + 8) = 15

x \to 7 - lim (\frac{1}{x - 7}) = - \infty

= 15 (- \infty)

Apply Infinity Property:

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

= - \infty

\int 4 sin (3 x) d x

\int_{0}^{0.5} 200 x d x

\frac{d}{d x} (x^{2} (3 - x)^{3})

\frac{\partial}{\partial x} (e^{x} tan (x - y))

\int \frac{cos ( x )}{6 - sin ( x )} d x
