Finger [1]

Answer:

x ---- y

1 ---- 3

4 ---- 12

6 ---- 18

Step-by-step explanation:

Given

y = 3x

Required

Create a table that represents this scenario

Because x represents time, x can not be negative. So, the domain of x is:

x \geq 0

Assume x = 1

y = 3 * 1 = 3

Assume x = 4

y=3*4 = 12

Assume x = 6

y=3*6 = 18

Hence, the table is:

x ---- y

1 ---- 3

4 ---- 12

6 ---- 18
