Question

Fill in the table using this function rule.

Answer 1

So the values of y at the given values of x are 15, 13,11 and 7

Explanation:

The function to use is

y = 19 -2x

now when x = 2

y will be y = 19-2(2) = 19-4 = 15

When x = 3

y = 19-2(3) = 19-6 = 13

when x = 4

y = 19 -2(4) = 19-8 = 11

when x = 6

y = 19-2(6) = 19-12 = 7
