Math Problem Statement
Solution
The image shows the graph of a quadratic function, which forms a parabolic curve. To answer the question about the domain and range using interval notation, let’s analyze the graph step by step.
Domain:
The domain refers to the set of all possible -values (inputs) for the function. The graph extends horizontally from to , meaning the function exists within these boundaries on the x-axis. Therefore, the domain in interval notation is:
Range:
The range refers to the set of all possible -values (outputs) for the function. From the graph, the highest point on the parabola occurs at (the vertex), and the graph extends downward to the lowest point, which is at . Thus, the range in interval notation is:
Let me know if you'd like further details or have any questions.
Here are 5 related questions for further exploration:
- How do you find the vertex of a parabola algebraically?
- Can you determine the equation of the function based on the graph?
- How would the domain and range change if the graph were shifted horizontally or vertically?
- What would the interval notation look like if the graph extended beyond or ?
- How can you determine whether the parabola opens upwards or downwards from the equation?
Tip: In a parabola , the sign of determines the direction the parabola opens: if , it opens upwards, and if , it opens downwards.
