Math Problem Statement

​(g) What is the domain of​ f?

Solution

The image shows a graph of a function f(x)f(x) with labeled points, including maxima, minima, and intercepts. To determine the domain of the function f(x)f(x), we need to look at the extent of the graph along the x-axis.

Domain Analysis:

The domain of a function consists of all the x-values for which the function is defined. Observing the graph:

  • The leftmost point on the graph is (28,6)(-28, -6), so the smallest x-value in the domain is x=28x = -28.
  • The rightmost point on the graph is (24,6)(24, 6), so the largest x-value in the domain is x=24x = 24.

Since the graph appears to be continuous between these two points without any breaks, the domain of f(x)f(x) includes all x-values from 28-28 to 2424.

Conclusion:

The domain of f(x)f(x) is the interval:

[28,24][-28, 24]

This means f(x)f(x) is defined for all x-values from 28-28 to 2424 inclusive.

Would you like further details or have additional questions?

Here are some related questions that might interest you:

  1. What is the range of the function f(x)f(x) based on the graph?
  2. How does the continuity of a function affect its domain?
  3. Can you describe a scenario where the domain of a function is restricted to specific values?
  4. What are the differences between open and closed intervals in a function's domain?
  5. How would the domain change if the graph had breaks or holes?

Tip: When determining the domain from a graph, always check for any gaps or vertical asymptotes that might restrict the x-values where the function is defined.
