What are the domain an range of function f (x) = 3^x+5

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.

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, ∞).
