Answer:
- y = 0
- A all real numbers
- E y > 0
- infinity
Step-by-step explanation:
1. The horizontal asymptote is the y-value the function approaches, but does not reach. That value is y = 0. This equation is the equation of that asymptote.
__
2. The domain is the horizontal extent of the graph. It covers "all real numbers." (A)
__
3. The range is the vertical extent of the graph. As we said in part 1, the value y = 0 is never reached, so the vertical extent (range) is y > 0 (E).
__
4. The graph extends upward indefinitely as x extends to the left indefinitely. That is, y → infinity.
