Question

What is the range of the function y= 2e^x -1 ?

Answer 1

The range is all real number greater than - 1

Answer 2

All real numbers greater than -1

Explanation:

We have to find the range of:

y=
`2e^x-1`

We know that
`e^x` lies in (0,∞)

Hence,
`2e^x` lies in (0,∞)

Hence,
`2e^x-1` lies in (-1,∞)

Hence, the range of y=
`2e^x-1` is:

All real numbers greater than -1
