Question

complete the table.
$f(k) = |-4k + 8|$

$k$	$f(k)$
3
5
7

Explanation:

Step1: Substitute k=1 into function

$f(1) = |-4(1) + 8| = |-4 + 8| = |4| = 4$

Step2: Substitute k=3 into function

$f(3) = |-4(3) + 8| = |-12 + 8| = |-4| = 4$

Step3: Substitute k=5 into function

$f(5) = |-4(5) + 8| = |-20 + 8| = |-12| = 12$

Step4: Substitute k=7 into function

$f(7) = |-4(7) + 8| = |-28 + 8| = |-20| = 20$

Answer:

$k$	$f(k)$
3	4
5	12
7	20
