Lucy's dog gave birth to a litter of 7 puppies. She plans to sell each puppy for $350. The function f(x)=350x can be used to represent this situation. What is the domain/ range of this function?

• Domain: {0, 1, 2, 3, 4, 5, 6, 7}

  Range: {0, 350, 700, 1050, 1400, 1750, 2100, 2400}

• Domain: {0, 350, 700, 1050, 1400, 1750, 2100, 2400}

  Range: {0, 1, 2, 3, 4, 5, 6, 7}

Give the domain and range of the relation.

• Domain: {-5, 4, 6}; Range: {-9, 9, 13}

• Domain: {4, 6, -5, 13, 9}; Range: {0}

• Domain: {-9, 0, 0, 13}; Range: {-5, 0, 4, 6}

• Domain: {-6, -4, 0, 2}; Range: {24, 17, 3, 10}
