Answer:
[A] It will take 24 minutes for Joe and Charmaine to meet again at the starting line.
[B] Joe will complete 2 laps
[C] Charmaine will complete 3 laps.
Step-by-step explanation:
Factor two numbers 12 and 8:
12 = 2×2×3
8 = 2×2×2
Find LCM of 12 and 8:
Lcm of 12 and 8 - 2×2×3×2 = 24
Therefore,
[A] How much time does it take for them to meet again at the starting line?
It will take 24 minutes for Joe and Charmaine to meet again at the starting line.
[B] How many laps does Joe complete
Joe will complete 2 laps
[C] How many laps does Charmaine complete?
Charmaine will complete 3 laps.

Answer:
<h2>This equation has no natural roots.</h2>
Step-by-step explanation:

For a linear function: The graph is a straight line
For a non-linear function: The graph is not a straight line
The given graph is not a straight line and is rather a curve with several turning points i.e several ups and downs. Hence the graph belongs to a Non-Linear Function.
A relation is non-function when it passes through same x value more than once. Since this cannot be observed in the given graph, the graph belongs to a function.
Therefore, the correct answer to this question is "Non-Linear Function"
