Question

Is this relation a function? (-3,4), (-2,5), (-1, 6) (-1,8)
15 points pleaseee

Answer 1

no

Explanation:

For the relation to be a function each value of x must map to exactly one unique value of y

Here - 1 → 6 ( - 1, 6) and

- 1 → 8 (- 1, 8)

That is the value of x = - 1 maps to more than one value of y, meaning the relation is not a function
