6-3: Exponential FunctionsExponential function is a function in the form f(x) =axwhere ais a positive real number and a ≠1. The domain of fis the set of all real numbers. The laws of exponents for real (irrational) exponents are the same as those for integer and rational exponents. Irrational exponents are truncated to a finite number of digits, so that ar≈ax.The number eis the number that 11+FHGIKJnnapproaches as n→∞. f(x) = axRangex-intercepty-interceptHorizontal asymptoteCharac-teristicPasses througha > 1(0, ∞)None(0, 1)x-axis as x →-∞Increasing, one-to-one(0, 1) (1, a)0 < a < 1(0, ∞)None(0, 1)x-axis as x →∞Decreasing one-to-one(0, 1) (1, a)Approximate to three decimal places:
