A function g is displayed in two windows.
• Window A: −2≤x≤2, −2≤y≤2 — the graph seems to approach y=3 as x→1.
• Window B: 0.8≤x≤1.2, 0≤y≤10 — the graph rises sharply without bound as x→1.
Which window provides the more reliable information about x→1limg(x), and what conclusion about the limit does that window support?
