Math Problem Statement

Find domain and range for the function

Find domain and range for the function shown in the image.

Solution

To find the domain and range of the function shown in the image, we can analyze the graph:

1. Domain:

The domain refers to the set of all possible input values (x-values) for which the function is defined.

  • From the graph, the parabola extends indefinitely to the left and right, meaning there are no restrictions on the x-values. Thus, the domain is: Domain=(,)\text{Domain} = (-\infty, \infty)

2. Range:

The range refers to the set of all possible output values (y-values) that the function can take.

  • The lowest point of the parabola, the vertex, appears to be at y=0y = 0, and the parabola opens upwards. Therefore, the function takes values from y=0y = 0 and increases indefinitely. Thus, the range is: Range=[0,)\text{Range} = [0, \infty)

Would you like more details on how to derive the domain and range from a graph, or do you have any other questions? Here are some related questions to deepen your understanding:

  1. How do we determine if a function's graph extends to infinity?
  2. What is the significance of the vertex in a quadratic function?
  3. How can we algebraically determine the domain and range of a function without graphing?
  4. How does the direction a parabola opens affect its range?
  5. What types of functions have limited domains?

Tip: When analyzing a quadratic function from its graph, the vertex is a key feature in determining the range, especially for parabolas.
