The statement in the image reads: "The y-intercept of the graph of the function \( y = f(x) \), whose domain is all real numbers, is \( f(0) \)."

This statement is **true**.

### Explanation:
The y-intercept of a function is the point where the graph crosses the y-axis. This occurs when \( x = 0 \). Thus, the y-coordinate of the y-intercept is given by evaluating the function at \( x = 0 \), which is \( f(0) \). So, if the domain of the function includes \( x = 0 \), the y-intercept is indeed \( f(0) \).

Would you like any further clarification?

1. What happens if the domain of \( f(x) \) does not include \( x = 0 \)?
2. How do you find the x-intercepts of a function?
3. Can a function have more than one y-intercept?
4. What is the y-intercept for linear functions like \( y = mx + b \)?
5. How can you determine intercepts for more complex functions (e.g., polynomials, rational functions)?

### Tip:
Always check whether a function’s domain includes \( x = 0 \) before assuming that the y-intercept is \( f(0) \).

The y-intercept of the graph of the function y = f(x), whose domain is all real numbers, is f(0).
