Question

D t

-60 0
-56 10
-24 90
-20 100
-8 130
0 150
Choose the correct statement.


Select one:

a.
The function is

D(t)=52t−150


b.
The function is

D(t)=25t−150


c.
The function is

D(t)=52t−60


d.
The function is

D(t)=25t−60

Answer 1

Answer: To determine the correct statement, you need to find a pattern in the values of D(t). You can do this by finding the difference between consecutive values of D(t).

The difference between -60 and 0 is 60.

The difference between 0 and 10 is 10.

The difference between 10 and 90 is 80.

The difference between 90 and 100 is 10.

The difference between 100 and 130 is 30.

The difference between 130 and 150 is 20.

The pattern that emerges is that the difference between consecutive values of D(t) is always 25. This means that the correct statement is "The function is D(t)=25t−60". The correct answer is therefore d.
