Math Problem Statement
Solution
The image contains a graph of a function and a series of questions about the function's properties.
Let's analyze each part step by step:
-
Question (a):
Is negative?
To answer this, we need to locate on the graph and see if the function value is below the x-axis. From the graph, appears to be negative because the graph is below the x-axis at .Answer: Yes, is negative.
-
Question (b):
For which value(s) of , is ?
To find where , we need to check the points where the graph intersects the x-axis. From the graph, the function appears to cross the x-axis at three points: , , and .Answer: .
-
Question (c):
For which value(s) of , is ?
This asks for the intervals where the function is either on or below the x-axis. From the graph, the function is below or equal to zero from to and from onwards. Using interval notation:Answer: .
Would you like further details or explanations on any part?
Here are five related questions you might find helpful:
- What is the significance of in real-world applications?
- How can you determine if a function is increasing or decreasing from a graph?
- What does it mean for a function to have a negative value at a particular -value?
- How do you express intervals where a function is negative using interval notation?
- How does the graph of a function help in identifying its domain and range?
Tip:
When analyzing a function graph, always check for x-axis intersections (roots), where the function is above or below the x-axis, and how it behaves at its critical points (maximums and minimums).
