8-3 Logarithmic Functions • What exponent would you have to use to: • change 2 to 8? • change 7 to 1? • change 5 to 25? • change 3 to 81? • change 4 to 0.25? • When you are determining the exponent you would need to change a number to something else, you are finding the logarithm. Logarithms are exponents.
