Math Problem Statement
Solution
The problem asks to identify specific intervals and points where the values of and (shown in the graph) meet certain conditions, such as when one function is greater or less than the other.
The functions are as follows:
- : the solid line graph.
- : the dashed line graph.
Let’s break down the different conditions based on the graph:
-
Intervals where :
- This is asking where the dashed line graph is below the solid line graph .
- By inspecting the graph, is below in the interval:
- These are the intervals where the dashed line lies below the solid line.
-
when :
- This asks to find the points where equals , i.e., where the solid and dashed lines intersect.
- Based on the graph, the functions intersect at and .
-
on the interval :
- This asks where the dashed line is above the solid line .
- The graph shows that between and , the dashed line is indeed above the solid line.
-
Intervals where on the interval :
- This asks where the solid line (solid graph) is below the x-axis (negative values).
- Inspecting the graph, we see that is negative for the interval:
- This means the solid line is below the x-axis between these values of .
Let me know if you want further clarifications or details.
Here are 5 related questions you could explore:
- What happens if we find intervals where both and are positive?
- How would the intervals change if we were looking for ?
- Can we generalize how to find intersections of two graphs in more complex functions?
- What transformations would shift above in all intervals?
- Can we determine the areas under and between given intervals?
Tip: Always sketch the graph yourself to visually check where one function is above or below the other to avoid mistakes in reading the graph.
