Choose the situations that state an appropriate domain for the function. A function predicts the number of square feet in a house in terms of the number of bedrooms. An
appropriate domain for the function is positive real numbers.
A grocery store sells salmon by the pound. The function C(x) represents the cost, in dollars, of x pounds of
salmon. An appropriate domain for the function is positive rational numbers.
A ball was thrown into the air with an initial velocity of 65 feet per second. The height of the ball after t
seconds is represented by the equation h = 65t - 16t? An appropriate domain for the function is positive
rational numbers.
A taxi company charges $2.50 plus $1.75 for each mile driven. A function C(x) shows how much a taxi fare
cost. An appropriate domain of C(x) is all whole numbers.
Lindsay's lemonade stand sells lemonade for $0.75 per cup. Her daily profit is modeled by P(c) = 0.75c -
8.5 where profit, P, is a function of cups, C. An appropriate domain of P(c) is all integers.
