WebNov 10, 2024 · Step 1. The function f(x) = x2 − 3x 2x2 − 5x − 3 is undefined for x = 3. In fact, if we substitute 3 into the function we get 0 / 0, which is undefined. Factoring and canceling is a good strategy: lim x → 3 x2 − 3x 2x2 − 5x − 3 = lim x → 3 x(x − 3) (x − 3)(2x + 1) Step 2. For all x ≠ 3, x2 − 3x 2x2 − 5x − 3 = x 2x + 1.
