the linear function f(x) = 0 5 + 80 represents the average test score in your math class, where x is the number or the test taken. the linear function g(x) represents the average test scores in your science class, where x is the number of the test taken.

I really do not understand what you are asking but I believe that the best website to get the anwser is photo math! or math papa really helps! Hope this help

i do not know this sorry : (
