limit as x approaches-infinity of-2^x-7

x \to - \infty lim (- 2^{x} - 7)

- 7

Solution steps

x \to - \infty lim (- 2^{x} - 7)

x \to a lim [f (x) \pm g (x)] = x \to a lim f (x) \pm x \to a lim g (x)

With the exception of indeterminate form

= - x \to - \infty lim (2^{x}) - x \to - \infty lim (7)

x \to - \infty lim (2^{x}) = 0

x \to - \infty lim (7) = 7

= - 0 - 7

Simplify

= - 7
