Question
Finding the limit graphically
Limits may not exist:
• if the values near x = a cannot 'agree' on a common y-value, the limit might not
exist
• consider approaching along f from the left
• and then consider approaching from the right
• do our two approaches "come together"?
• if they come together, then we say the limit equals the matching output as we
approach from each side
• if they do not come together, we say the limit “does not exist" (DNE)
