What was the graph of the equation x equals negative 4 look like

It will be a vertical line parallel to y-axis, passing through point , the graph is shown below.

Step-by-step explanation:

Mark the point , it will lie on x-axis.

Drop a perpendicular line passing through parallel to y-axis.

That is the require graph.

Dwould be the answer

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
