Answer 1

The graph below shows the distance (y) between Hannah and her home, in km, after a certain time (x), in hours:

Graph of first line going through ordered pairs 0, 4 and 2, 4. Graph of second line going through ordered pairs 2, 4 and 3, 2. Graph of third line going through ordered pairs 3, 2 and 4, 4. Graph of fourth line going through ordered pairs 4, 4 and 6, 4.

Which of the following statements best describes Hannah's distance from her home?

It is decreasing in the interval 2 < x < 4 hours.
It is increasing in the interval 2 < x < 3 hours.
It is decreasing in the interval 2 < x < 3 hours.
It is increasing in the interval 2 < x < 4 hours.

Answer 5

The intervals are simply the coordinate points

In this case the graph is continuous from (0,2), but from (2,4) there is a decrease in hannahs path. then from (4,6) its back to being continuous.

So Hannah's decreasing in the interval 2 < x < 4 hours.

Answer 8

The first four terms of a sequence are shown below:

9, 5, 1, -3

Which of the following functions best defines this sequence?

f(1) = 9, f(n + 1) = f(n) - 4; for n ≥ 1
f(1) = 9, f(n + 1) = f(n) + 4; for n ≥ 1
f(1) = 9, f(n + 1) = f(n) - 5; for n ≥ 1
f(1) = 9, f(n + 1) = f(n) + 5; for n ≥ 1
