Answer:
(0,∞)
Step-by-step explanation:
Given: [tex]f(x)=9^x[/tex]
It is an exponential function whose base is 9.
If base is greater than 1 then function is growth exponential.
Domain: All real value of x.
Range: It is output value of function we get by putting x.
For x approaches to infinity , y → ∞
For x approaches to negative infinity, y → 0
Range: All positive real number.
Range: (0,∞)
Hence, The range of the given function is (0,∞)
