Answer:

The domain is (all possible values of x)
\{0,1,2,3,4,5\}

The range is (all possible values of f(x))
\{250,200,150,100,50,0\}

Explanation:

A contestant on a game show is given $250. He is asked five questions and loses $50 for every wrong answer.

  • If he answer all 5 questions correct, then he will still have $250;
  • If he answers 4 questions correct and 1 question incorrect, he will have $200;
  • If he answers 3 questions correct and 2 questions incorrect, he will have $150;
  • If he answers 2 questions correct and 3 questions incorrect, he will have $100;
  • If he answers 1 question correct and 4 questions incorrect, he will have $50;
  • If he answers 5 questions incorrect, he will have $0.

Let x be the number of wrong answers. Then you get a relationship


\begin{array}{cc}x&f(x)\\ 0&250\\1&200\\2&150\\3&100\\4&50\\5&0\end{array}

The domain is (all possible values of x)
\{0,1,2,3,4,5\}

The range is (all possible values of f(x))
\{250,200,150,100,50,0\}
