Which is the range of the function f(x) =(9)x?
2 answers:
Answer:
(0,∞)
Step-by-step explanation:
Given:
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,∞)

Answer:
3) ,
Step-by-step explanation:
Given that the explicit rule for a sequence is .
Now we need to find about what is the recursive rule for the sequence and match with the given choices to find the correct choice.
1) ,
2) ,
3) ,
4) ,
Plug n=1 into given formula to get first term
base of the exponent part is (-2) so that means we need to multiply -2 to the previous term to get nth term
Hence correct choice is: 3) ,
