Correct:$f(2,1) = \min\{6\cdot2,8\cdot1\} = \min\{12,8\} = 8$.
Go on.
Antwoord 2 feedback
Wrong: The idea is not take the minimum of the two input variables.
See Minimum functions and the corresponding Extra explanation.
Antwoord 3 feedback
Wrong: 12 is not the minimum of the two elements between brackets.
See Minimum functions and the corresponding Extra explanation.
Antwoord 4 feedback
Wrong: $\min\{6\cdot2,8\cdot1\} \neq 6\cdot2-8\cdot1$.
See Minimum functions and the corresponding Extra explanation.
