Could someone please check my work

Please state all definitions and theorems that you will need: Definition 5.1.1 Let f: D x F and let' be an accumulation point of D. We say that a real number L is a limit of for each 5 \\ () there exists a 6 w () such that ]f(.z) e L| 0 361, 62 > 0 such that 0if(;c)M| 0. Since c is an accumulation point of D , there exists an a: E D such that O [R and c is an accumulation point of D , then f can have only one limit at c . In other words, the limit of a function, if it exists, is unique
