Answer:
(A) f(x) = 2 *
Step-by-step explanation:
[] We can find our answer by plugging the x values into the functions as t and solving.
-. Using this method, starting with the A function, we find that the first function models the data and we do not need to test the others. I still have shown the work for the others as it is good to check your work.
[✓] f(x) = 2 *
(1, 8) }{}{}{ f(x) = 2 * = 2 * 4 = 8
(2, 32) }{}{}{ f(x) = 2 * = 2 * 16 = 32
(3, 128) }{}{}{ f(x) = 2 * = 2 * 64 = 128
-> This pattern continues
[✗] f(x) =
(1, 8) }{}{}{ f(x) = = 4 ≠ 8
-> This function does not model the data as it does not fulfil the first point
[✗] f(x) = 4 *
(1, 8) }{}{}{ f(x) = 4 * = 4 * 2 = 8
(2, 32) }{}{}{ f(x) = 4 * = 4 * 4 = 16 ≠ 32
-> This function only models (1, 8) but does not fully model the data
[✗] f(x) =
(1, 8) }{}{}{ f(x) = = 8
(2, 32) }{}{}{ f(x) = = 64 ≠ 32
-> This function only models (1, 8) but does not fully model the data

Given:
The scatter plot and trend line.
To find:
Type of association, slope, equation of trend line and average cost of apple per pound.
Solution:
Form the given graph it is clear that the trend line passes through the two points (0,0) and (12,24).
Slope of trend line is
Slope of trend line is positive. It means, it represents positive correlation.
So, the type of association of the scatter plot is positive association.
Therefore, the slope of trend line is 2.
The trend line passes through (0,0) have slope 2, so the equation of the trend line is
Therefore, the equation of trend line is .
Slope of the line is 2.
Therefore, the average cost of apples per pound is $2.
