Consider the problem of predicting how well a student can perform in a university, given his/her middle school and high school GPAs. Specifically, let 1 and 2 represent a student's GPAs received in middle school and high school, respectively. We would like to predict the value of , which is defined as the possible GPA the student would get in the university. The hypothesis is () = 0 + 11 + 22 and cost function is denoted as (0, 1, 2). If we use the training set listed in the following table, calculate (0,1,0). 1: 3, 2, 3, 4

x2: 3, 2, 4, 4

y: 4 1 3 4
