Answer 1

Answer:

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.

Answer 2

Answer:

part a: 79.4 (math)

part b: 84 (science)

part c:            math                                       science 

test 2-  f(2) = 0.2(2) + 79 = 79.4     //   86  84   82  80

test 4-  f(4) = 0.2(4) + 79 = 79.8    //   1     2     3     4

In other words, for test #4, the test average for science was 80% and for math it was 79.8. So, science had a higher test average.
