limit as x approaches-infinity of 2^x+3

x \to - \infty lim (2^{x} + 3)

3

Solution steps

x \to - \infty lim (2^{x} + 3)

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 (3)

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

x \to - \infty lim (3) = 3

= 0 + 3

Simplify

= 3
