algebra one linear functions

Question

the linear function f(x) = 0.5x + 80 represents your 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 and your science class, where x is the number of the test taken

part a: determine the test average for your math class after completing test two

part b: determine the test average for your science class after the completing test 2.

part c: which clause had a higher average after completing test 4?

Answer 1

I'm assuming g(x) is a graph. Along the x-axis is the test number and along the y-axis is the average.

After one math test, the average is 0.5(1) + 80 = 80.5, etc. Look at g(x). What is y when x = 1? That's the science average after 1 test.

Go.
