Answer:
We conclude that The domain is represented by age.
Thus, the option 'c' is true.
Explanation:
We know that the domain of a function is the entire set of input values of the independent variable 'x' for which the function remains real and defined.
Given the attached graph, we can observe that height is dependent on age (years). In other words, the age (years) is basically an independent variable.
Therefore, we conclude that The domain is represented by age.
Thus, the option 'c' is true.
