Consider the following computational problem  AlteredMult:   Input -10 <=  x  <= 30, x ∈ Z; 12 <= y <= 24, y ∈ Z    Output the integer 3*x - 7*y The following correct choices for x and y for Boundary Value Analysis C_x =(-10, -9, 1, 29, 30) C_y = (12, 13, 20, 23, 24) and the test suite I:   Test Name x y Expected result  T1 -10 20 -170 T2 -9 20 -167 T3 1 20 -137 T4 29 20 -53 T5 30 20 -50 T6 1 12 -252 T7 1 13 -273 T8 1 23 -483 T9 1 24 -504

Consider the following computational problem 

AlteredMult:

  Input -10 <=  x  <= 30, x ∈ Z; 12 <= y <= 24, y ∈ Z 

  Output the integer 3*x - 7*y

The following correct choices for x and y for Boundary Value Analysis

• C_x =(-10, -9, 1, 29, 30)
• C_y = (12, 13, 20, 23, 24)

and the test suite I:

WHICH ANSWERS ARE CORRECT AND WHAT MEAN choice a)

a)  C_x and C_y are combined in such a way that they yield all input combinations required for Boundary Value Analysis. 

b) There is at least one expected result that is correctly calculated from the values given for x and y.

c) There is at least one correct combination of C_x and C_y for Boundary Value Analysis.

d) All expected results are correct.
