#### Continuity and Uniform Continuity

It is obvious that a uniformly continuous function is continuous if we can nd a which works for all x 0, we can nd one the same one which works for any particular x 0 We will see below that there are continuous functions which are not uniformly continuous Example 5 Let S= R and f x = 3x 7 Then fis uniformly continuous on S Proof ....Know More
