    Read 4.1-2

    If a > 0 and b > 1, then the function y = abx is an exponential growth function, and b is called the
    growth factor. You will graph exponential growth functions in the form y = bx, y = abx, and
    y = abx – h + k for b > 1. You will find compound interest and account balances using the
    compound interest equation.

    If a > 0 and 0 < b < 1, then the function y = abx is an exponential decay function, and b is called the
    decay factor. You will graph exponential decay functions in the form y = bx, y = abx, and
    y = abx – h + k for 0 < b < 1.
