Question #3a12a

Answer 1

`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]}
