Rebecca has 30 paintings to sell. the amount of money rebecca makes from selling x paintings is represented by a function.
f(x)=25xf(x)=25x
what is the practical domain of the function if rebecca sells 30 paintings?
1. all real numbers
2. all integers from 0 to 30, inclusive
3. all multiples of 25 between 0 and 750, inclusive
4. all integers from 0 to 25, inclusive

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.

where, x is number of painting to sell.

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.
