Let a be a real number. Then, lim x → ap(x) = p(a) lim x → ap(x) q(x) = p(a) q(a) when q(a) ≠ 0. To see that this theorem holds, consider the polynomial p(x) = cnxn + cn − 1xn − 1 + ⋯ + c1x + c0.

Use the graph of y = f ( x) in the figure below to determine the following limits: lim x → 1 f ( x) lim x → 2 f ( x) lim x → 3 f ( x) lim x → 4 f ( x) When x is very close to 1, the values of f ( x) are very close to y = 2. In this example, it happens that f ( 1) = 2, but that is irrelevant for the limit.
