Answer:
[tex]D=(-\infty,\infty),[N|N\in\mathbb{R}][/tex]
[tex]R=(-\infty,\infty),[R|R\in\mathbb{R}][/tex]
Step-by-step explanation:
Given : Ann thought of a number N, multiplied it by 5 and added 7. Then she told the result R to Jim.
To find : The Domain and Range of this function.
Solution :
Ann thought of a number N,
Multiplied the number by 5 = 5N
Added 7 = 5N+7
Result is R = 5N+7
The function form is [tex]R=5N+7[/tex]
The Domain is where the function is defined.
The domain of the given function is
[tex]D=(-\infty,\infty),[N|N\in\mathbb{R}][/tex]
The range is the set of value that corresponds to domain.
[tex]R=(-\infty,\infty),[R|R\in\mathbb{R}][/tex]
