Question

x1 2 3 2 Does the table represent a function? Y 1 4 9 -4

Answer 1

Function, domain and range

x = 1. 2. 3. 2

y = 1. 4. 9. -4

THEN analyze table

If in a table, x values are REPEATED, then this table does NOT represent a function

For example, in this case ,number 2 is repeated two times

Then, for this reason, this table IS NOT a function
