Question

What is the range for f(x) = 2^x

Answer 1

Given the function:

$f(x)=2^x$

The function can also be written as:

$y=2^x$

The range of the function will be all set of y values.

To find the range, let's graph the function below.

We have:

From the graph above, all possibe y values range from 0 to infinity.

Therefore, the range of the function is from zero infinity.

In interval notation:

Range = (0, +∞)

ANSWER:

4. (0, +∞)
