Question

What is the range of the function y=e^x+1 graphed below

a. y>0
b. y<0
c. y>1
d. y<1

Answer 1

1. The graph of the function
`y=e^x` is shown in attached diagram.

2. The graph of the function
`y=e^x+1` can be obtained from the graph of the parent function
`y=e^x` by translation 1 unit up.

3. The range of the parent function
`y=e^x` is y>0 (see attached diagram for details). Thus, the range of the function
`y=e^x+1` is y>1.

Answer: correct choice is C.

Answer 2

The range of y=e^x+1 is y>1.
