### Explanation of Solution

Given information: consider the function f(x)=x1

Calculation:

Machine diagram of f:

If x is in the domain of the function f , then when x enters the machine, it is accepted as an input and the machine produces an output f(x) according to the rule of the function. Thus, it can think of the domain as the set of all possible inputs and the range as the set of all possible outputs. Take the values of the function f(x)=x1 for the estimate values of the variable x

Plug the value x=2, in the function f(x)=x1 then the value of f(2).

f(2)=21f(2)=1

Plug the value x=5, in the function f(x)=x1 then the value of f(5).

f(5)=51f(5)=4f(5)=2
