Make an input-output table to represent the function. use 1, 2 , 3, 4, and 5 as the domain. y = 3x + 9

pls!

When x = 1, y  = 3(1)  + 9 = 3 + 9 = 12
when x = 2, y  = 3(2)  + 9 = 6 + 9 = 15
when x = 3, y  = 3(3)  + 9 = 9 + 9 = 18
when x = 4, y  = 3(4)  + 9 = 12 + 9 = 21
when x = 5, y  = 3(5)  + 9 = 15 + 9 = 24

table
input            output
1                    12
2                    15
3                    18
4                    21
5                    24

17 is c. congruent means equal in size
