Limits of fuctions as x approaches a constant
When a function f is defined by some expression on some reduced neighborhood of a real number a, if we substitute a into this expression and it makes sense, then the outcome is the limit of f at a.
Look at the sample:
But, as you compute limits of functions as x approaches a constant, you can find several possible solutions:
- The limit is equal to a constant
- The limit is plus or minus infinity
- The limit does not exit
Try to compute the following limits:
