Problem A4 | |
|
The graph is not linear, because it's not a straight line, and the difference between consecutive outputs is not constant. The graph is also not exponential, because it does not increase or decrease indefinitely, and the ratio between consecutive outputs is not constant. Neither is the graph quadratic, because the difference between consecutive outputs is not linear, nor are the second differences constant.

Problem A8 | |
|
Yes, this is a cyclic function, because its outputs are repeated consistently over time. The period is one heartbeat.

Problem A9 | |
|
The period is the length of one hearbeat, which can be measured in seconds or fractions of a minute. In this graph, the period is about 0.9 seconds. The amplitude is half the difference in pressure from the lowest point to the highest point, usually measured in mm Hg (millimeters of mercury), and in this graph is (140 - 60)/2, or 40 mm Hg.
