Unformatted text preview: c circlecopyrt Kendra Kilmer February 3, 2009 Section 3.1  Introduction to Limits Definitions: LeftHand Limit: We write lim x → c − f ( x ) = K if f ( x ) is close to K whenever x is close to, but to the left of c . RightHand Limit: We write lim x → c + f ( x ) = L if f ( x ) is close to L whenever x is close to, but to the right of c . (TwoSided) Limit: We write lim x → c f ( x ) = L if the functional value f ( x ) is close to L whenever x is close, but not equal, to c (on either side of c ). Note: For a (twosided) limit to exist, the limit from the left and the limit from the right must be equal. That is Example 1: Use the graph below to find the following limits: 4 5 2 3 11234554321 2 1 3 4 5 6 666 f(x) a) lim x →− 3 − f ( x ) f) lim x → 1 f ( x ) b) lim x →− 3 + f ( x ) g) lim x → 4 − f ( x ) c) lim x →− 3 f ( x ) h) lim x → 4 + f ( x ) d) lim x → 1 − f ( x ) i) lim x → 4 f ( x ) e) lim x → 1 + f ( x ) 1 c circlecopyrt Kendra Kilmer February 3, 2009...
