Below are tables for two functions, $f$ and $g\text{.}$ The function $f$ is invertible, but the function $g$ is non-invertible. In the last problem, you decided why a certain table was non-invertible. In general, a function is non-invertible if: ? At least one output value is repeated No output values are repeated In general, a function is invertible if: ? At least one output value is repeated No output values are repeated
