A myFun1 B myFun2 Neither myFuni nor myFun2 D Both myFun1 nor myFun2 The grades of the students in a class are calculated by using a MATLAB function which would use following rules: [020]-->F; (20 40]-->D; (40,60]--> C, (60 80]-->B; (80 100]-->A. We assume that the written program will have inputs between 0 and 100. For the following problem consider two functions that have been written to satisfy these rules. These two functions are given below (Note: "U]" means the number is included while "( )" means the number is excluded.) function (grade] = my Fun1 (x) if x
