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

Answer:

All real numbers greater than -1

Step-by-step 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
