WebAdd a comment 1 Observe that x − 1 x − 1 = sgn ( x − 1), so f ( x) = x − 1 ( x − 1) ( 2 x + 1) = sgn ( x − 1) 2 x + 1 = sgn ( x − 1) g ( x) = { g ( x) x > 1 − g ( x) x < 1 where g ( x) = 1 2 x + 1 → 1 3 as x → 1 ±. You have a discontinuity in x = 1 and the limits are lim x → 1 ± f ( x) = ± 1 3. Share Cite Follow WebFeb 15, 2010 · To solve an undefined limit, see examples 5 and 6 of limits that need simplification. If direct substitution yields ∞/∞, undefined, then divide by the highest power. lim 3x + 1 x→∞ 5x + 6 The limit exists even though the function is undefined. The limit for this example is 3/5.
