Answer:

#(x|x " is " RR}# or #(-oo,oo)#

Explanation:

Domain has no restrictions so it is all real numbers:

#(x|x " is " RR}# or #(-oo,oo)#

Range is more interesting, it has a asymptote at -10 so it gets closer and closer to -10 but never gets there so it is:

#{y|y > -10}# or #(-10, oo)#

graph{e^(-x)-10 [-13.58, 26.42, -12.96, 7.04]}
