The table shows the percent of US households with computers for selected years between 1984 and 2003. Which of the equations shown EHVW models the data in the table, where y is the percent of households with computers and x is the number of years after 1980?

The functions f and g are defined as shown. The values of x for which f(x) = g(x) lie in which of the intervals shown? Select THREE that apply.

• the yearly interest rate for the account

• the amount of the initial deposit in the account

• the number of years it takes for the account value to reach $1500

• the number of years it takes for the initial amount in the account to double

• No, because c would equal -2, and the points (-2, 0) and (3, 0) would not be on the graph of y = P(x).

• Yes, because c would equal 2, and the points (1, 0) and (3, 0) would be on the graph of y = P(x).

• Yes, because c would equal –2, and the points (1, 0) and (3, 0) would be on the graph of y = P(x).

• No, because c would equal 2, and the points (1, 0) and (3, 0) would not be on the graph of y = P(x).

• The processing fee consists of a fixed amount of $0.15 plus 0.35% of the purchase amount.

• The processing fee consists of a fixed amount of $0.15 plus 3.5% of the purchase amount.

• The processing fee consists of a fixed amount of $0.35 plus 1.5% of the purchase amount.

• The processing fee consists of a fixed amount of $0.35 plus 15% of the purchase amount.

• x = 9 only

• x = -9 and x = 9
