Your domain is all the values x can take on, in this case all the real numbers.
Your range is everything you can get by raising 3 to a real number, which would be the positive real numbers.

for every x , 3^x > 0 so that is the range. all positive real numbers

all positive real numbers because it is like a logarithmic
equation which is good for all positive real numbers.
Also if x = 1/2, g(x) is the square root of 3 which is not a rational number.

All positive real numbers or g(x)>0.
