QuestionIdentify which of these are functions: $f(x)=|x-5|$ and the set $\{(-5,6),(-2,8),(0,4),(8,8)\}$.

Studdy Solution
Looking at the set of ordered pairs, we see that each input is paired with exactly one output. Therefore, this set also represents a function.
So, both $f(x)=|x-|$ and $\{(-,6),(-2,8),(0,4),(8,8)\}$ represent functions.
