Correct:$f(10,8) = \min\{10, 2\cdot 8\} = \min\{10,16\} = 10$.

Go on.
Antwoord 2 feedback
Wrong: The idea is not to take the minimum of the two input variables.

See Minimum functions and the corresponding Extra explanation.
Antwoord 3 feedback
Wrong: 16 is not the minimum of the two elements between brackets.

See Minimum functions and the corresponding Extra explanation.
Antwoord 4 feedback
Wrong: $\min\{10,2\cdot8\} \neq 10 - 2\cdot8$.

See Minimum functions and the corresponding Extra explanation.
