0, if x=5
5−x, if x< 5
2x+7
a) if x > , then 2x + 7 =
b)if x = , then 2x + 7 =
c) if x < , then 2x + 7 =
(x−4)+7
if x > , then (x − 4) + 7 =
if x = , then (x − 4) + 7 =
if x < , then (x − 4) + 7 =
7−(x−7)
if x > , then 7 − (x − 7) =
if x = , then 7 − (x − 7) =
if x < , then 7 − (x − 7) =
7−(12−x)
if x > , then 7 − (12 − x)=
if x = , then 7 − (12 − x =
if x < , then 7 − (12 − x)=
