Question 1039859: I really need help on this problem please!
Let f(x) = e^–x – 1.
Answers can be stated without additional work/explanation.
(a) Which describes how the graph of f can be obtained from the graph of y = ex ? Choice: ________
A. Shift the graph of y = e^x to the left by 1 unit and down by 1 unit.
B. Shift the graph of y = e^x to the right by 1 unit and down by 1 unit.
C. Reflect the graph of y = e^x across the x-axis and shift down by 1 unit.
D. Reflect the graph of y = e^x across the y-axis and shift down by 1 unit.
(b) What is the domain of f ?


(c) What is the range of f ?


(d) What is the horizontal asymptote?


(e) What is the y-intercept?



(f) What is the graph of f ?
I really appreciate the help on this. I believe I can find the asymptote once I have some other information as well as the range and domain, thank you so much for any help!
