# Question #9ec0f

For the graph, y = tan x, the lines x = (2n + 1)$\frac{\pi}{2}$ are asymptotes that are never met by the curve, For closer x, the curve is nearer.
The lines x = (2n + 1)$\frac{\pi}{2}$ and the curve y = tan x have no common points at all..
The value could ever increase/decrease without limit, within a period $2 \pi$. So, the range is said to be infinite.
