Identify Point of Interest: Identify the point of interest on the graph where x approaches the specific value. Check the behavior of f(x) as x gets closer to this point from both the left and the right.
Check Behavior of f(x): Observe the y-values that f(x) approaches from the left-hand side and the right-hand side. If these values agree, the limit exists and is equal to this common value.
Observe Approaching y-Values: Record the y-value approached by f(x) as x approaches the specific value. This is the limit of f(x) at that point.
Record Limit Value: Verify calculations by rechecking the graph to ensure no mistakes were made in observing the limit.
