Answer:
D: all real numbers
R: (5, ∞)
Step-by-step explanation:
D: you can plug in anything for x and it makes sense. You can raise 3 to any real power (2, 1/2, -10 etc) and get an answer.
R: Because 3^x only produces positive numbers, the range is (0+5, ∞) ---> (5, ∞).
Answer:
Domain (-∞, ∞).
Range (5, ∞).
Step-by-step explanation:
The domain is all real values of x or in interval notation (-∞, ∞).
The 3^x can only have a value greater than 0.
So the range is f(x) > 5.
