The step-by-step analysis leads to the conclusion that the domain of function \(m\) is \((-∞, ∞)\), indicating that the function is defined for any real number input.
1. Given Information:
 - The function represented by the graph is 
 , which is a quadratic function.
, which is a quadratic function.
 - The graph extends infinitely in both directions without breaks or gaps.
2. Understanding Domain:
 - The domain of a function is the set of all possible input values for the function.
3. Analysis of the Graph:
 - The graph shows a quadratic function without any apparent restrictions on the x-values.
4. Conclusion:
 - Since the graph represents a quadratic function 
 without any breaks or gaps, the function is defined for all real numbers.
 without any breaks or gaps, the function is defined for all real numbers.
5. Final Answer:
 - The domain of function \(m\) is all real numbers, which can be represented as \((-∞, ∞)\).
