Domain $(- \infty, \infty)$ $(-oo, oo)$ . Range : $(- \infty, 0)$ $(-oo, 0)$ . See graph and explanation.

$y = - {(\frac{1}{5})}^{x} < 0 and \to 0$ $y=-(1/5)^x<0 and to 0$ , as $x \to \infty$ $x to oo$ .

y-intercept ( x = 0 ) : $- 1$ $-1$

As $x \to - \infty, y \to - \infty$ $x to -oo, y to -oo$ .

So, domain is $(- \infty, \infty)$ $(-oo, oo)$ and range is $(- \infty, 0)$ $(-oo, 0)$
