Exponents and Exponential Functions I can: (where we should be today) Apply exponent properties involving products Apply exponent properties involving quotients Define and use zero and negative exponents Use scientific notation Write and graph exponential growth functions Write and graph exponential decay functions

Big ideas Expression Property am · an = am+n (am)n = amn (ab)m = ambm Product of powers property (am)n = amn Power of a power property (ab)m = ambm Power of a product property am/an = am-n a = 0 Quotient of powers property (a/b)m = am/bm b = 0 Power of a quotient property

Define and use zero and negative exponents Words Algebra Example a to the zero power is one a0 = 1 a=0 50 = 1 a-n is the reciprocal of an a-n = 1/an a=0 2-1 = ½ an is the reciprocal of a-n an = 1/a-n, a=0 2 = 1/2-1
