Question

Fill in the table using this function rule. y= 3x + 4

x- 3,6,7,8
y- blank

Answer 1

y: 13, 22, 25, 28

ordered pairs: (3, 13) (6, 22) (7, 25) (8, 28)

Explanation:

Given:

• function: y = 3x + 4
• values of x: -3, 6, 7, 8

To find the y-values, substitute the x-values into the function and solve.

when x = 3

y = 3(3) + 4

= 9 + 4

= 13

when x = 6

y = 3(6) + 4

= 18 + 4

= 22

when x = 7

y = 3(7) + 4

= 21 + 4

= 25

when x = 8

y = 3(8) + 4

= 24 + 4

= 28

Therefore, the ordered pairs are; (3, 13) (6, 22) (7, 25) (8, 28)
