Graph two periods of the given tangent function. y = tan(x − π/4)

The graph of a cotangent function is given. Select the equation for each graph from the following options: y = cot(x + π/2), y = cot(x + π), y = −cot x, y= −cot(x − π/2).

In Exercises 55–58, use a graph to solve each equation for -2π ≤ x ≤ 2π. tan x = -1
