Document Summary
= l f (x) lim x a as y l. This means that the limit of x a be real numbers. L a y = f (x) (x) as be a function of approaches x y = f. February 8, 2019 x is equal to a. L (dr. allison) x > 1 x < 1 f f (x) (x) decreases to 4. increases to 4. Example: lim x 1 x + 3 = 4 from values of from values of x 1 x 1. Formally: one sided limits lim x 1+ x + 3 = 4 lim x 1 . February 8, 2019 lim x 2 x + 2 x x 6. Find the limit, if the limit exists: 0, 1. 1: 5, the limit does not exist. Cross out common multiples in the numerator and denominator. X = 2 lim x 2 x + 2 x x 6. Note: there is a hole due to a removable discontinuity at.
