Let's calculate the function values for $f(a) = |a| + 2$.

Given values of $a$:

1. $a = 5$
   $f(5) = |5| + 2 = 5 + 2 = 7$
2. $a = 10$
   $f(10) = |10| + 2 = 10 + 2 = 12$
3. $a = 15$
   $f(15) = |15| + 2 = 15 + 2 = 17$
4. $a = 20$
   $f(20) = |20| + 2 = 20 + 2 = 22$

Completed Table:

$a$	$f(a)$
5	7
10	12
15	17
20	22

Tip:

Absolute value functions create V-shaped graphs because they reflect negative inputs to positive values.
