Math Problem Statement
Identify the x- and y-intercepts of the functions graphed below.
Solution
Let's analyze the graphs and determine the - and -intercepts for each of the given functions:
1. Graph 1:
- -intercept(s): The graph touches the -axis at approximately , so the -intercept is .
- -intercept: The graph crosses the -axis at approximately , so the -intercept is .
2. Graph 2:
- -intercept(s): The graph crosses the -axis at three points: , , and . So, the -intercepts are .
- -intercept: The graph crosses the -axis at approximately , so the -intercept is .
3. Graph 3:
- -intercept(s): The graph does not touch or cross the -axis, so there are no -intercepts.
- -intercept: The graph crosses the -axis at approximately , so the -intercept is .
4. Graph 4:
- -intercept(s): The graph touches the -axis at and , so the -intercepts are .
- -intercept: The graph crosses the -axis at approximately , so the -intercept is .
5. Graph 5:
- -intercept(s): The graph crosses the -axis at and , so the -intercepts are .
- -intercept: The graph crosses the -axis at approximately , so the -intercept is .
6. Graph 6:
- -intercept(s): The graph does not touch or cross the -axis, so there are no -intercepts.
- -intercept: The graph does not cross the -axis, so there is no -intercept.
Would you like further details or clarifications?
Here are five related questions to deepen your understanding:
- How do you find the - and -intercepts algebraically from an equation?
- Why do some graphs have no - or -intercepts?
- How can symmetry of a graph help in identifying intercepts?
- What are the characteristics of a function with multiple -intercepts?
- How do vertical and horizontal asymptotes affect the intercepts of a graph?
Tip: The -intercept is found when , and the -intercept is found when . Always substitute these values into the function to verify the intercepts algebraically.
