Determine limit fx as x 1 Determine limit fx as x 1 542 3

Determine: limit f(x) as x --> 1-

Determine: limit fx) as x --> 1+

Solution

1) Since graph on the left of 1 which means slightly less than one approaches 20 so

  limit f(x) as x --> 1- is equal to 20

2) Since graph on the right of 1 which means slightly greater than one approaches 2.5 so

limit fx) as x --> 1+ is equal to 2.5
