Short Answer

State what it means for a function f to be left continuous at a point x = c, in terms of the delta–epsilon definition of limit.

The function f to be left continuous at a point x = c, in terms of the delta–epsilon definition of limit is limxcf(x)=L for all number ε>0, there exists some real number δ>0 such that if xc-δ,c we have f(x)f(c)-ε,f(c)+ε.

Step by Step Solution

Step 1. Given Information. 

The function f is left continuous at a point x=c.

Step 2. Stating. 

The function f to be left continuous at a point x = c, in terms of the delta-epsilon definition of limit.

Let f(x) be a function defined on the interval that contains x=c, then the limit limxcf(x)=L for all number ε>0, there exists some real number δ>0 such that if xc-δ,c we have f(x)f(c)-ε,f(c)+ε.
