Question

You hit 9) Consider the set of related x and y values. Which value of g would make it impossible for the set to represent a function? {(8. 67), (5, 28), (g. 19), (9,84)}

Answer 1

Remember that for any value on the domain of a function, there can only be one value on the range that assigns to it.

We have the set:

$\mleft\lbrace(8,67\mright),(5,28),(g,19),(9,84)\}$

therefore, a value of g that make it impossible for the set to represent a function can be 8, 5 or 9, since those values already have another value assigned from the range.
