A stock loses half its value each week. If the stock started at $125, what is it worth after 4 weeks?

Answer: 7.81

The formula is

y = 125* (1/2)^4

y = 125 / 16

y = 7.81

So at the end of the 4th week, the stock is worth only 7.81 dollars.

If that is not the motive and the first week doesn't count then the formula changes to...

y = 125 * (1/2)^(n-1)

y = 125 * (1/2)^3

y = 15.625 could be the other answer if you looked at it in that perspective

However, I would go with 7.81 as the answer.

Hope I helped :)

Answer:

Linear function with rate of change/growth = 2.5, which agrees with the fourth statement listed in the answers options.

Step-by-step explanation:

Notice that both columns of reported x and y values are increasing.

Then examine how the given x-values  increase:

-2, 2, 6, 10, 14  (in steps of 4 units)

and how their corresponding y-values increase:

-2, 8, 18, 28, 38  (in steps of 10 units)

therefore, if we do the rate of change for any pair (x_1,y_1) and (x_2,y_2), we get the following constant rate of change:

\frac{y_2-y_1}{x_2-x_1} = \frac{10}{4} =2.5

Given that this relationship is valid for any pair of (x,y) values. we conclude that the rate of increase is constant, and therefore we are in the presence of a linear function, whose rate of change is 2.5
