limit as x approaches infinity of-4^x

x \to \infty lim (- 4^{x})

- \infty

Solution steps

x \to \infty lim (- 4^{x})

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

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

Apply the common limit:

x \to \infty lim (a^{x}) = \infty, a > 1

= - \infty

\int \frac{1}{( 1 - u ^{2} ) ^{\frac{3}{2}}} d u

\int \frac{1}{1 - x} d x

\frac{d}{d x} (e^{s i n (3 x^{2})})

\int x 2 x - 3 d x

\int 9 tan^{5} (x) d x
