    Graph y = 2^-x for -2 <= x <= 2.

    Solve for x: 3^4x-5 = 27.

    Suppose $1000 is invested at 6 percent annual interest, compounded monthly. How many dollars wil be in the account after:
    a) one year?
    b) five years?

    Write in exponential form (log_9)(27) = 3/2.

    Write in logarithmic form: 1296 = 6^4.

    At 5% interest compounded yearly, how many years foes it take for your money, say $1, to quadruple? [Hint: Solve (1.05^t) = 4 for t by taking a logarithm.]
