Let f(x)=e^x and g(x)=x-3 what are the domain and range of (f g) (x)
a. domain: x> 0 range: y< 0
b. domain: x> 3 range y> 0
c. domain: al real numbers range: y< 0
d. domain: all real numbers range: y> 0

D. domain: all real numbers range: y>0

Step-by-step explanation:

The composite function of f(x) and g(x) is:

y = f(g(x))

In this problem, we have that:

So

The domain of an exponential function is all real numbers, and the range are positive values.

So the correct answer is:

D. domain: all real numbers range: y>0
