Question

algebra 1 > m.4 identify functions vll
look at this table:

x	y
10	8
11	11
12	-11
-6	8

is this relation a function?
yes no

Explanation:

Step1: Recall function definition

A relation is a function if each input (x - value) has exactly one output (y - value).

Step2: Check x - values

Look at the x - values in the table: 10, 10, 11, 12, - 6. The x - value 10 appears twice, with corresponding y - values - 6 and 8. Since one input (x = 10) has more than one output, the relation does not satisfy the definition of a function.

Answer:

no
