Answer:
Option B , C and D are correct.
The values of k are 12.1 , 13.0 and 19.9
Step-by-step explanation:
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 .

Answer:
Step-by-step explanation:
From the graph, the x-intercepts are;
These are root of the polynomial function represented by the given graph.
By the remainder theorem;
According to the factor theorem, if is a factor of
, then
This implies that;
are factors of the required function.
Hence;
We expand using difference of two squares to obtain;
We expand using the distributive property to get;
Rewrite in standard form to obtain;
