The linear function f(x) 0.2+ 79 represents the average test score on your math class, where x is the number of test taken. The linear function g(x) represents the average test score in your science class, where x is the number of test taken.

Complete question :

The linear function f(x) = 0.2x + 79 represents the average test score in your math class, where x is the number of the test taken. The linear function g(x) represents the average test score in your science class, where x is the number of the test taken.

Step-by-step explanation:

Average score for math ckasaafter completing test 2:

Put x = 2 in linear model:

f(2) = 0.2(2) + 79 = 79.4

Part B;

The average score for science after completing test 2 ; from the table ;score corresponding to g(x) = 2 is 84

Part C:

Substitute x=4 in f(x) to get the test average for Math class :

f(4) = 0.2(4) +79 = 79.8

Science ckass:

From the, table xg(x), the score decreases by 2 as the Number of test x, increases the

Hence, after test 4 ; average score for science = 82 - 2 = 80%

g(x) is a linear function, and from the table we understand that as x increases by 1, g(x) decreases by 2.

Continuing that pattern, when x=4, g(x) = 80

80% > 79.%
