Table I contains outputs of the function ${f}({x})=b^{x}$ for some ${x}$ values, and Table II contains outputs of the function ${g}({x})=\log _{b}(x)$ for some ${x}$ values. In both functions, ${b}$ is the same positive constant.

Fill in the missing values in the tables. If necessary, round your answer to three decimal places. You do not need a calculator.
