complete the table. f(x) = 2x - 9

Explanation:

Step1: Substitute x = 5

$f(5)=2\times5 - 9$ $=10 - 9$ $=1$

Step2: Substitute x = 6

$f(6)=2\times6 - 9$ $=12 - 9$ $=3$

Step3: Substitute x = 7

$f(7)=2\times7 - 9$ $=14 - 9$ $=5$

Step4: Substitute x = 8

$f(8)=2\times8 - 9$ $=16 - 9$ $=7$

Answer:

x	f(x)
5	1
6	3
7	5
8	7
