x=pi/4k

Explanation:

you can ignore the 7 because multiplying csc(4x) by a constant doesn't change whether a y-value exists at that point or not.

csc(x) is discontinuous when x=pik, where k is a constant.

that means csc(4x) is discontinuous when 4x=pik or x=pi/4k

so the graph of F(x)=7csc(4x) is discontinuous when x=pi/4k

graph: graph{7csc(4x) [-7, 7, -11, 11]}
