79.4 ; 84 ;science class
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.%
