Answer 2

Answer:

Option 2 is correct.

Step-by-step explanation:

Rebecca has 30 paintings to sell.

The amount of money Rebecca makes from selling x paintings is represented by a function.

$f(x)=25x$

where, x is number of painting to sell.

As we are given total number of painting for sell is 30.

Domain: It is input value of x where function and situation defined.

Minimum number of painting she could sell be 0 and Maximum number of painting she could sell be 30.

Domain:  0≤x≤30

Hence, All integers from 0 to 30, inclusive.
