# Math Help - fixed points

1. ## fixed points

Determine the fixed points (if any).

T(x,y)=(x,2)

2. This does not belong here. But you are looking for the pairs $(x,y)$ such that $T(x,y)=(x,y)$, i.e. $(x,2)=(x,y)$. Thus we must have $y=2$ and there is no restriction on $x$ (i.e. $x\in \mathbb{R}$).
