Question

What are the domain and range of the exponential function below?
f(x) = 3^x + 2

Answer 1

Domain: all real numbers

Range: all real numbers greater than 2

Explanation:

The domain of a function is the set of numbers that have a corresponding function value. Because this function is an exponential function, its domain is all real values.

The range of a function is the set of values that the function can output. Because
`3^x` will never be equal to or less than 0, the range of this function is all numbers greater than 2.
