Evaluate each limit. If the limit does not exist, say so but also state if y is approaching positive or negative infinity. Homework Help ✎
Which problems above can be interpreted as the definition of the derivative at a point?
Simply evaluate at x = 0.
You can multiply the top and bottom by the conjugate:
You might have noticed that this is Ana's definition of the derivative:
Rewrite the given limit as:
Deconstruct the definition:
Write the derivative equation:
Evaluate at x = 1:
a = 1
This is Hana's definition of the derivative.
a = 25
