As x approaches 2 from the left, y approaches 2+3 (or 5) from below. But because of the open parenthesis at the right of (-infinity, 2), as well as the jump in y value (from 5 to 1) at x =2, the limit does not exist.
Answer: A,D,E
Step-by-step explanation:
Let’s walk through this with every possible option.
A: The input is the x axis, and since there is no x value that is used twice, this is true.
B: No. It is higher at 30 seconds than at 31 seconds, meaning that as time increases, the height does not always increase.
C: No. You cannot determine the time based on height. For example, at a height of 40, you don’t know if it’s at 20 or 40 seconds.
D: Yes. Assuming the picture on the left corresponds, it is a circle. Once you get to the original point, which is at 60 seconds, it will start all over again.
E: The time is the x axis, and the title is height, so yes.
