Math Problem Statement
Answer the questions below based on the graph of the quadratic function f, of, xf(x) and a table of selected values of the quadratic function g, of, x, .g(x)
Solution
Thank you for sharing the graph and table. I will go through the details of each function and based on the provided information. Here’s what we can infer from each component:
Observations about the Graph of :
- The function shown in the graph appears to be a quadratic function due to its parabolic shape.
- The parabola opens upward, indicating that the leading coefficient of the quadratic function is positive.
- The vertex of seems to be located at approximately , which suggests that the minimum value of occurs at .
- The axis of symmetry for the graph is likely .
- The function appears symmetric about this axis, as expected for a quadratic function.
Observations about the Table for :
The table provides values of for specific -values. We can analyze these values to understand the function .
-3 | 35 |
-2 | 21 |
-1 | 11 |
0 | 5 |
1 | 3 |
2 | 5 |
3 | 11 |
- The values in the table suggest that also represents a quadratic function because the outputs (values of ) follow a parabolic trend.
- The smallest value of occurs at , with . This indicates that the vertex of is likely at .
- The values are symmetric around , which is a common feature of quadratic functions centered at their vertex.
- Based on the table, also appears to be an upward-opening parabola, similar to .
Questions
Based on the graph and table, please answer the following questions:
- What is the minimum value of according to the graph?
- What is the vertex of the function based on the table?
- Do and have the same vertex?
- At which points do and share the same -values for corresponding -values?
- Is the symmetry of and about their respective vertices consistent?
Tip:
When analyzing quadratic functions, identifying the vertex is crucial, as it reveals the function's maximum or minimum point and helps understand the symmetry of the function.
