Correct, but please don't start a new thread for the same question. I have deleted the new thread.ttpp1124 said:My answer for 12b:
If the limit exists, it’s the derivative of 𝑓 at 𝑥=−2. But, the limit doesn’t exist. To see this, calculate the one-sided limits as h approaches zero from the right, and from the left. They both exist, but they are not the same, so the limit does not exist, meaning 𝑓 is not differentiable at 𝑥=−2
A limit is a fundamental concept in calculus that represents the value that a function approaches as its input approaches a certain value. It is denoted by the notation "lim f(x) as x approaches a."
A limit is defined using a graph by looking at the behavior of the function as the input values get closer and closer to the specified value. The limit is the value that the function gets closer and closer to, but may not necessarily reach.
A graph can help find the meaning of a limit by visualizing the behavior of the function and identifying any patterns or trends. It can also provide a visual representation of the limit and help determine its value.
Understanding limits is crucial in calculus as they are used to define important concepts such as continuity, derivatives, and integrals. They also allow us to solve complex problems involving rates of change and optimization.
One common misconception is that the limit is equal to the value of the function at the specified point. However, a limit may not necessarily be equal to the function value. Another misconception is that a function must be defined at the specified point in order for a limit to exist, but this is not always the case.
