Option B , C and D are correct.
The values of k are 12.1 , 13.0 and 19.9
Given the inequality: .
The boundary point is not included when the inequality is less than ‘<‘ or greater than ‘>’, and is represented by an open circle on the boundary point.
Also, the arrow goes to the right when the inequality symbol is greater than (>) or greater than equal .
since, the inequality as shown in figure below;
The solution of k which satisfy k > 12 are;
12.1 , 13.0 and 19.9 .
