Answer 1

Answer:

The set of Real number less than -5.

Step-by-step explanation:

Given:

$f(x) = -3^{x}-5$

For finding the range we will put the value for $x=-1,0,1,2,.....$

∴ $f(-1) =-3^{-1}-5\\=\frac{-1}{3} -5\\=\frac{-16}{3}\\=-5.333$

∴ $f(0) =-3^{0}-5\\=-1 -5\\=-6$

∴ $f(1) =-3^{1}-5\\=-3 -5\\=-8$

and so on we have all the set of Real number less than -5.
