Question
Determine if the set is a function, a one-to-one function, or neither. Reverse all the ordered pairs in each set and determine if this new set is a function, a one-to-one function, or neither.$$\{(0,5),(-4,5),(-4,2),(0,2)\}$$
Step 1
A set is a function if each input (x-value) is paired with exactly one output (y-value). Looking at the given set $\{(0,5),(-4,5),(-4,2),(0,2)\}$, we can see that the inputs 0 and -4 are each paired with two different outputs. Therefore, the given set is not a Show more…
