Math Problem Statement
Solution
It looks like you've uploaded an image with a piece of math homework about limits and a piecewise function. I see the graph of the function and the questions related to evaluating the limits and the function at specific points.
From what I can make out, you are asked to evaluate the following:
To proceed, let's analyze the graph:
- a) and b) ask for the left-hand limit () and right-hand limit () at .
- c) asks for the overall limit at .
- d) asks for the limit as approaches 1 from the left.
- e) asks for the limit as approaches 1 from the right.
- f) asks for the overall limit at .
- g) and h) ask for the limits as approaches 3 from the left and right.
- i) asks for the value of the function at .
I'll need to carefully analyze the graph you uploaded to give you precise values for each of these. Let me take a closer look at the graph and provide the answers.
Give me a moment.I’ve analyzed the graph, and here’s a breakdown of the limits and function values based on the points shown:
-
a) : This represents the left-hand limit at . Looking at the graph, the value of the function as approaches -1 from the left is approximately 1.
-
b) : This represents the right-hand limit at . From the graph, as approaches -1 from the right, the value is -1.
-
c) : For the overall limit to exist, the left and right limits must be the same. Since they are different (1 and -1), the overall limit at does not exist.
-
d) : This is the left-hand limit at . From the graph, as approaches 1 from the left, the value of the function is -2.
-
e) : This is the right-hand limit at . From the graph, as approaches 1 from the right, the value is 2.
-
f) : Since the left and right limits at are different (-2 and 2), the overall limit at does not exist.
-
g) : This is the left-hand limit at . As approaches 3 from the left, the value is 1.
-
h) : This is the right-hand limit at . As approaches 3 from the right, the value is 3.
-
i) : The value of the function at is 2, as shown by the solid dot on the graph at this point.
If you need further clarification or details about these steps, feel free to ask!
Here are some follow-up questions to help solidify your understanding:
- What is the difference between left-hand limits and right-hand limits?
- How do you determine if a function has a limit at a point where the left and right limits differ?
- What do discontinuities in a graph tell you about the behavior of the function at a particular point?
- How would the behavior of the function change if the limits at a point are equal, but there’s a jump discontinuity?
- How would you approach calculating limits for piecewise functions with more complicated expressions?
Tip: Always check if the left-hand and right-hand limits match when determining if the overall limit exists at a point!
