Question

Ann thought of a number N, multiplied it by 5 and added 7. Then she told the result R to Jim.

Answer 1

Answer:

$D=(-\infty,\infty),[N|N\in\mathbb{R}]$

$R=(-\infty,\infty),[R|R\in\mathbb{R}]$

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 $R=5N+7$

The Domain is where the function is defined.

The domain of the given function is

$D=(-\infty,\infty),[N|N\in\mathbb{R}]$

The range is the set of value that corresponds to domain.

$R=(-\infty,\infty),[R|R\in\mathbb{R}]$
