Domain: all real values of x
Range: f (x) > 0
Step-by-step explanation:
f (x) = 3^x
There's no domain restriction, so x can take any real value
Tye graph f (x) has a horizontal asymptote at y = 0 because with a positive base, the output can never be 0 or negative
Hence the range is y > 0

Below in bold.
Step-by-step explanation:
x can have any real value - the domain is (-∞, ∞).
f (x) cannot be 0 or negative, no matter how negative x is, - the range is (0, ∞)
