Question

fill in the table using this function rule.
y = 3x + 3
x | y
4 |
6 |
7 |
8 |
try one last time

Explanation:

Step1: Substitute x = 4 into y = 3x + 3

$y = 3\times4 + 3 = 12 + 3 = 15$

Step2: Substitute x = 6 into y = 3x + 3

$y = 3\times6 + 3 = 18 + 3 = 21$

Step3: Substitute x = 7 into y = 3x + 3

$y = 3\times7 + 3 = 21 + 3 = 24$

Step4: Substitute x = 8 into y = 3x + 3

$y = 3\times8 + 3 = 24 + 3 = 27$

Answer:

When x = 4, y = 15; when x = 6, y = 21; when x = 7, y = 24; when x = 8, y = 27.
So the completed table is:

x	y
6	21
7	24
8	27
