Jason is selling video games. to earn his monthly bonus, he must sell a minimum of 5 games. he has 30 he can sell. the video games cost $20 each. the function f(x) = 20x can be used to represent this situation. what is the practical range of the function? all whole numbers from 5 to 30, inclusive. all whole numbers from 100 to 600, inclusive. all real numbers. all multiples of 20 between 100 and 600, inclusive.

Correct choice is B

Step-by-step explanation:

The function represents the situation, where x is the number of sold video games and f(x) is the total cost of sold games.

Jason  must sell a minimum of 5 games, this means that He has 30 video games he can sell, then Thus, the domain of the function is

The range of the function f(x) is

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

answer: 5100 just subtract
