1. What is the y-intercept of y = tan x?
2. What is the y-intercept of y = cot x?
3. For what numbers, -2π ≤ x ≤ 2π, does the graph of y = tan x have vertical asymptotes?
4. For what numbers, -2π ≤ x ≤ 2π, does the graph of y = cot x have vertical asymptotes?
Use transformations to graph each function.
5. y = -cot x
6. y = tan(x –

)
